I discovered a Fossil on the Beach and Puzzled
Up to date on March 22, 2017 Kathi moreContact Writer Discovering Common Fossils on Great Lakes Beaches
A favorite previous time for many is combing the beaches for attention-grabbing objects the surf washes in. Whether you’re walking alongside the shoreline of the ocean or the great Lakes within the USA, your imagination is on excessive alert to select something up you just can’t cross by! Abruptly, one thing catches your eye! But, it isn’t driftwood or seashore glass or even a reasonably rock. You could not know precisely why, but you suspect you found something that was once a dwelling creature.
Has this ever occurred to you A deep sense of curiosity and childlike imagination drives us to find out what we could have picked up along our saltwater or freshwater shorelines. Having collected quite a number of samples from Lake Michigan’s shoreline, myself, I finally decided in the future to fulfill my nagging curiosity and adopted by way of with a rewarding investigation. The more I discovered about my stony sand-smoothed findings, the more I needed to know. I wondered what the creatures may have looked like when alive and the way they survived. I additionally wanted to know how they showed up so prevalent along the fresh water beaches. Some time later, after many answered questions, I can truthfully say I get pleasure from a cool passion. Taking things a step further, I have drawn illustrations of their dwelling beings and began a fossil site. You’ll find the hyperlink at the end.
Some of essentially the most prevalent fossils found alongside the great Lake’s beaches are crinoids (proven in the photos to the appropriate). They’ve been coined with a a number of names due to the animal’s features and by the character of their fossils found all through historical past. One common name for them is “Indian Beads”. Native People were identified to make necklaces with their damaged up items which resemble the shape of beads perfect for stringing. They’ve also been known as “Lucky Stones”! Spotting one takes a keen eye as a lot of the items are quite small.
As dwelling creatures, every circular section was stacked one over the other constructing the animal’s complete framework. They possessed branching arms that sat atop long single stems. They were sessile creatures, in other phrases, they remained attached to the sea flooring. Some varieties are identified to have towered several meters in length. Their unfastened structure resulted in the dwelling organism’s beautifully coloured and flower like look which granted them the nickname of “Sea Lilies”. They captured tiny meals particles passing by on ocean currents with their feathery network of arms that functioned like traps. Crinoids match into the phylum of Echinoderm, which means spiny pores and skin, and are cousins of starfish, sea urchins and feather stars.
Sea lily crinoid’s lengthy history began in the course of the Ordovician Period round 500 million years in the past, though most fossils are from the Mississipian Period around 345 mya and are preserved in limestone. Immediately there are far fewer species and most lack the long meandering stem frequent in Paleozoic varieties.
Within the course my investigation, I had usually puzzled why so many crinoid fossils ended up along the nice Lakes; particularly by the fact that they’d thrived in saltwater environments. I’ve since learned they are often found widespread in North America. Part of the answer to my inquiry is simple sufficient to explain. During their lifetime, a lot of the world’s continents were covered under heat shallow oceans, together with elements of North America. So how is it their fossils are so widespread close to the big lakes The answer is because ten thousand years in the past when the large glaciers sculpted the deep basins forming the nice Lakes, in addition they dug into the deep layers where their stays rested. In the method, they were deposited where we now can uncover them and revel of their secrets, as well as that of different species from the identical period.
Another frequent beach discover, bryozoans are often called lace corals due to their delicately threaded look, however they aren’t true corals. Instead, they are moss-like animals belonging to the family of Fenestellida for his or her fan-shaped, mesh look. They dwell in tight colonies sculpted by laborious, limy, branching structures. The colony consists of 1000’s of particular person animals called “zooids”. Each individual zooid lives inside its own limy tube called a zooecium. The zooecium are the dimensions of sewing needles. A single zooid begins the colony. A bryozoan colony has been observed growing from a single zooid to 38,000 in just five months. Every further zooid is a clone of the very first one.
Attention-grabbing how they feed, Each zooid has an opening through which the animal can lengthen its ring of tentacles known as lophophores. Their lophophores capture microscopic plankton from the water passing by. If one zooid receives food, it nourishes the neighboring zooids because they’re joined by strands of protoplasm. If solely we humans may very well be more like them making certain everyone on the planet is fed!
Their fossil file dates again 500 mya with 15,000 known species. Immediately there are about 3,500 dwelling species.
I discovered these clam fossils on the shore of Oval Seashore in Southwestern Michigan. The shell of the darker sample has been completely replaced by minerals and is petrified to stone. Its easy floor is a telltale demonstration of the lake’s sand and water action. The lighter colored sample clearly reveals the hardened muddy sediment that has fully encrusted its shell.
“Clam” is usually a term that covers all bivalves. Some clams bury themselves in sand and breathe by extending a tube to the water’s surface. Bivalve oysters and mussels attach themselves to laborious objects and scallops can free swim by flapping their valves together. Every kind lack a head and usually don’t have any eyes, though scallops are a notable exception. With the usage of two adductor muscles they’ll open and close their shells tightly. Very fittingly, the phrase “clam” gives rise to the metaphor “to clam up”, which means to stop talking or listening.
Bivalves have occupied Earth as early as the Cambrian Period 510 million years in the past, however they have been particularly ample in the course of the Devonian Period around four hundred million years in the past. Their fossils are discovered in all marine ecosystems and most commonly in near shore environments. In 2007, off the coast of Iceland, a clam was discovered to be a minimum of 405 years previous. It was declared the world’s oldest dwelling creature by North Wales, Bangor College researchers.
No different organisms typify the Age of Invertebrates more than brachiopods. They are probably the most plentiful Paleozic fossils, except for maybe trilobites. Paleontologists use them up to now rocks and different fossils. Numerous billions accumulated on the ocean ground with over 30,000 types. Immediately there are far fewer species, solely about 300 which stay mostly in cold water, deep ocean environments.
Brachiopods appear like clams however are very completely different inside. To inform them apart, clams have uneven formed shells, but each prime and bottom halves are an identical. Brachiopods are symmetrical at a look, but the underside shell is smaller. Brachiopods are commonly known as “lampshells” resulting from their similarity in shape to a Roman oil lamp.
They dwell in communities connected to objects by a muscular foot referred to as a pedicle. They pressure water in and out of their shells filtering microorganisms with their lophophores, a crown of tentacles.
Through the Devonian time slot, over 350 million years in the past, Michigan was lined by a shallow saltwater sea. That’s where mass colonies of corals called Hexagonaria, percarinata, generally generally known as Petoskey Stones, thrived and flourished. The saltwater seascape must have been lit up with a quilt-work of colours by the mass colonies. Unfortunately, they turned extinct at the top of the Permian Interval’s mass extinction.
The identify “Petoskey” originated from an Ottawa fur-trader chief named Petosegay. A northern Michigan city was named after him, only the title was modified to Petoskey. Due to their abundance along Michigan shorelines, particularly in the northern areas near Petoskey, Governor George Romney signed a invoice in 1965 that made the Petoskey Stone the official state stone.
When observing one of the fossils, each coral hexagon structure, seen to the attention, held a single animal which opened a mouth to expose tentacles. The tentacles took in food and have been also used to sting any organism or other corallite that got here too shut. Calcite, silica and other minerals replaced the unique corallite exoskeleton.
An extinct order of coral known as tabulate corals additionally formed reefs and lived in heat shallow waters throughout the identical interval as the Petoskey Stone corals. They were the favosite corals. The tabulae (horizontal inside layers) had been built outward because the organism grew. These layers can clearly be seen in the photograph to the correct. The favosites can be identified by the honeycomb pattern on the exterior of their fossilized remains.
Hope you’ve got loved my fossil discoveries. Subsequent time you go to the seaside, keep your eyes open for a fossil discovery of your own. You’re welcome to make use of my hub or go to my fossil blog to assist make an identification!

Good introduction to fossils and fossil looking for beginners Kathi.
I like the road:
‘A deep sense of curiosity and childlike imagination drives a few of us to find out what we picked up along the freshwater shoreline.’
That is the unlucky level I feel. For some cause, as individuals grow out of childhood too many lose their childhood fascination for such things as fossils, in addition to different wonders like the creatures which dwell in a pond, or the stars to be seen within the night sky. That’s sad – if solely everybody may keep that sense of curiosity and imagination as they grow up – the world could be a way more wondrous place for all – adults, as well as kids.
I hope some at the very least really feel impressed as they stroll along a shoreline or beside a cliff face, to turn over a number of stones and see what they can discover. Alun

Sure, Fossillady, I did get pleasure from this. This has been an afternoon of studying. I have read so many attention-grabbing articles this afternoon and this one is certainly one I’ll remember. I had no concept. It is wonderful how much there is to find out about fossils.
Sending many Angels your means this afternoon. 🙂 ps

Your hubs are so pretty! Thanks dear Fossillady!
Ha, What are you aware, I am a geo-jokster and do not even realize it…hee
Ha fossillady one thing new…LOL and were talking about fossil Ha that is an incredible geo-joke…
Extraordinarily happy with this discussion Tom and Birdy, learned one thing new!!!!!
I assume it is like a tree with the circles. Attention-grabbing.
I am pretty certain the accretion strains on the highest of a clam will reveal its age-just like the rings on a tree the clam gets greater and another ring is added-

I will speak fossils with you any day. I’m in touch with each sides of my brain! Typically I surprise myself, lol.
“In 2007, off the coast of Iceland, a clam was discovered to be a minimum of 405 years previous. It was declared the world’s oldest living creature by North Wales, Bangor College researchers.” How do they know this and where is the clam at now How does one decide the age of a clam that has seen centuries pass Oh, I think a poem just got here to thoughts. Both sides of that brain are reacting at the identical time.
Thanks for an important and nicely researched Hub.
Very form of you Janet! I had never labored with pastels before so there’s lots of room for enchancment, they’re principally targeted for youngsters! Subsequent time you are at the seaside or in nature I hope you possibly can acknowledge a few of these fossils!

Very fascinating hub,Fossillady !Very informative and I like the artwork! It is awesome.I by no means knew some of these have been fossils! Properly,I positive learned one thing tonight!
Thanks for sharing both information and art…nice combo!
i know its kinda humorous I always appreciated Ross too and my spouse would at all times take a look at me when he would say something geological…
don’t worry- publish a fossily hub i’ll learn it…
ya received one fan…its a begin
I know what you imply, nobody wants to talk about fossils with me both. Jogs my memory of Ross on Associates. He at all times needs to share his details about fossils and the others will not have something to do with it!lol
I’m just glad to talk fossils ith someone- my youngsters likem however.. even they tire of looking fast
Great recommendation Tom, Very much appreciated!
When cleansing crinoids- ya gotta know what kinda rock is clinging to them- will depend on the rock sort you findem in round here it iseasily found in shale i normally rtry to clip off- the best i can with toe nail clippers – watch out- then i will use a reasonably dilute HCL resolution between .1 and .25 dilute-use a “comfortable wire brush” perhaps nylon brush-ajust hcl to rockhardness- always use acid in wellventilated space use safety glasses and neoprene or nitrile gloves- sandstone embeds- can be picked off the crinoids and a remaining acid wash
Hi Workingmom, Good to see you right here! I wish I had advise for cleansing stone island jacket yoox fossils, I’d think so long as you don’t use something too harsh,will probably be okay!
It seems like it isn’t all that arduous for you to seek out the crinoids where you might be! I get so excited every time I can spot Island one! lol…take care!

Love this hub! I used to be truly eager about writing a hub about crinoid beads (truly about using them to create jewelry, since I do this). My husband is an novice archaeologist (aka rock hound), and he began taking me with him once we first started relationship. I didn’t care a lot about discovering the arrowheads that he was searching, but I fell in love with the beads! We have been simply down in Monroe Co.KY, and found quite a number of inside a few minutes by some of the numerous creeks. By the way in which, have you learnt a very good technique for cleansing fossils I need to wash those beads if I’ll make jewellery out of them!
Hi Tom,Oh it feels like a rick fossil find space. I have never discovered a trilobite, my husband did as soon as while engaged on the railroad. I like to search out crinoids which might be still attach, nevertheless it could be even higher to find one absolutely intact! Thanks for stopping by!
Now we have the sme devonian aged fossils close to Lake Erie- that shallow sea was actually big when my son went hunting with me he stated what are all these nuts and washers doing here-on the ground in fact we were in a crinoid rich space. There were a ton of Brac’s s properly-then we found some smaller trilobite halves and a had an ideal time diggin the dirt and shale shards He kept pulling up shale and asking what it was then he gave me one with a Trilobite hint fossil (imprint) it was actually a great one
Hello WillStarr, You made your youngsters feel very special that day! A beautiful fatherly factor to say. I would like to go to Kentucky and check out the shale financial institution. Kentucky has several fossil websites I’ve examine! I acknowledge you from other hubs and that i see you’re now following me, right again at ya!

The Kentucky farm the place we lived for just a few years had a shale bank on one facet of a stream that was loaded with fossils. My kids had been fascinated once i instructed them they have been looking on the beginnings of life on Earth, and that their eyes had been the first human eyes to ever see what that they had discovered.
Great, I am glad you made a new discovery, I hope you find lots of fossils! It really is enjoyable when you discover one! It is gratifying later when you’ll be able to establish it!

Wowwee! Great hub. I reside in Lengthy Island New York, the place there are miles and miles of beaches. I never knew among the things I was looking at might be fossils. When the weather is hotter I will revisit your hub to look and be taught extra. Thanks for educating me. Rated up and awesome.
My jaw dropped while you talked about coelacanth fish that was found! I’ve learn that too! I might love to come there and fossil hunt. I’ve by no means been throughout the ocean. Hope to try this earlier than my day comes around!
Nell Rose 6 years in the past from England
Hi, you should come over to England, you’ll have a terrific time! lol the last time I went to Lyme Regis, Jurassic coast, they had been filming for Television, and they’d a fossil programme crammed with all that they had found, I might imagine that there are nonetheless a great deal of what we imagine to be extinct animals still on the market dwelling in the deep ocean, I remember reading that fishermen discovered a coelacanth fish nonetheless residing again in 1933, and i imagine they have caught a few more since then, so that you by no means know! cheers nell
Properly, you have got made my day and i hope yours is full of love and joy! Hugs

As a matter of truth I am working on one partly because of your encouragement! It is way appreciated!
..Hello Kathi – sure I like to stroll alongside my beach in the spring, summer time and fall and pick up ‘found objects’ and flotsam and jetsam washed in from the tide particularly after a storm or high winds however as I speak there’s a lot snow and ice down there right now you can’t see something besides an enormous blanket of white – all over the place you look – I think about I will have to wait till the spring now to find something new and get back to my days of ‘beachcombing’ …….in case you have any more images about your days on the seaside or just round where you live it can be good to see you make another photographic hub on that topic ……

I can not help however feel sorry for poor deaf kitty, but I’m sure he/she’s in good palms. We’ve got the same lake effect on the west coast of Michigan brought on by the westerly winds. In actual fact we’re in a snow belt area. Final couple of years we’ve had report snowfall over one hundred twenty inches. Do you choose up fossils while you stroll the beach Thanks again in your assist!

…absolutely fascinating hub topic you’ve got written about right here …. I live on the northern shores of Lake Erie in Ontario, Canada and that i stroll on a regular basis along my seaside with my deaf cat (on a leash). I dwell 100 ft away from the lake ……and that i at all times see flotsam and jetsam and found objects which are washed up every day whether or not it’s man made or miracles of natures.
By the way in which how is the weather the place you reside
We often get what is called lake effect situations because of the winds off the lake.
Once more you’ve really finished some wonderful analysis here in your hub and would be a worthy addition in any classroom!
