Alp Posted August 3, 2022 Share Posted August 3, 2022 Hello everyone! I am new here and this is my first post. Today i have found a rock that i suspected of carrying a fossil inside. So i gave it a shot and broke it open only to my surprise finding a fossil inside. After some research i was not able to identify this earthworm looking like creature. I found this forum and wanted to ask your opinions on this case. The fossil is 17mm long and 3 mm thick. It is found in a rooftop which has different rocks for decorative purposes so i do not know where it originally came from. I am located in the middle of Turkey (Anatolia) Would be great to at least have an understanding of this creature from the earths past days. Thank you all in advance and hey i hope i am welcome here!

Shellseeker Posted August 3, 2022 Share Posted August 3, 2022 Definitely welcome here... You recognize the difference between a rock and a fossil ... you have a fossil.. I am not skilled on the fauna in your part of the world , but maybe @Tidgy's Dad can help.... 1 The White Queen ".... in her youth she could believe "six impossible things before breakfast" Link to comment Share on other sites More sharing options...

Thank you so much Shellseeker! I hope we can identify this one i am curious about these things :) I am adding more detailed photos with this reply Link to comment Share on other sites More sharing options...
grandpa Posted August 3, 2022 Share Posted August 3, 2022 Welcome to the forum. My first impression is that this is a crinoid crown with long arms that are partially worn away. 2 1 Link to comment Share on other sites More sharing options...

Thank you for your opinion and quick response! @grandpa, but my research has showed me that the crinoid crowns have rather vertical lines just like a spine where as my found has horizontal lines. And also i would like to point out that the fossil seems to have both ends attached it looks like a flat earthworm. Link to comment Share on other sites More sharing options...
Plax Posted August 3, 2022 Share Posted August 3, 2022 perhaps a distorted and weathered echinoid spine? Link to comment Share on other sites More sharing options...

But closer inspection with my eye shows me that both ends are converging and creates conical ends It does not seem to be attached to anything else.

Plax Posted August 3, 2022 Share Posted August 3, 2022 perhaps a large foram then? 1 Link to comment Share on other sites More sharing options...
minnbuckeye Posted August 3, 2022 Share Posted August 3, 2022 Echinoid spines come in MANY sizes and shapes. I would not rule this out. Spines. External ornament: A , Paracentrotus (echinoid), “smooth”. B , Prionocidaris (cidaroid), scattered, coarse thorns. C , Stylocidaris (cidaroid), row of thorns. D , Eucidaris (cidaroid), beaded ribs. E , Diadema (diadematoid), verticillate. F , Asthenosoma (echinothurioid), hyaline hoof. Cross sections: G , Eucidaris (cidaroid), differentiation in central medulla, lamellae and cortex. H , Asthenosoma (echinothurioid), hollow spine with labyrinthic mesh. I , Diadema (diadematoid), hollow spine with well-defined basal plate. J , diadematoid with occasional trabeculae crossing central lumen. K , Paracentrotus (echinoid), dissepiments linked by thin pillars. L , Brissopsis (spatangoid), hollow spine with well-defined basal plate. General appearance: M , Echinodiscus (scutelline), aboral spine with swollen, bent head. N , Histocidarid, specialized adoral primary spine with saw-tooth edges. O , Brissopsis (spatangoid), spatulate-tipped spine in two views. Black scale bars equal 100 μ m, white scale bars 1 mm.

I see how it is plausible but the ends seem too irregular for an echinoid spine. Link to comment Share on other sites More sharing options...

My first impression is that this is a crinoid crown with long arms that are partially worn away. @grandpa After further research, I think you might be absolutely right! I am sorry for being ignorant and not understanding what you meant at first. I have found some examples and some fossils have indeed converging ends just like closed tentacles of a squid when it is swimming. In the first image the ends look very similar but it is a fatter one. In the second image i can see that the horizontal and vertical lines are very similar In the third image (a) we can see that both ends can be conical. (All images are taken from public sources i do not own any rights to any one of those 3) What do you guys think? Link to comment Share on other sites More sharing options...

BobWill Posted August 4, 2022 Share Posted August 4, 2022 I recently learned that fusulinids can actually get that big. We usually think of them as microfossils since they are a single cell but they can reach as long as 5 cm. I think there is a part of the structure that could account for the fine lines running across the surface that you can see in this image from Wikipedia. 3 1 Link to comment Share on other sites More sharing options...
Tidgy's Dad Posted August 5, 2022 Share Posted August 5, 2022 I don't know fossil collecting in Turkey at all, I'm afraid. But to me fusulinid looks the best suggestion thus far. 1 Life's Good! Tortoise Friend. Link to comment Share on other sites More sharing options...
IsaacTheFossilMan Posted August 6, 2022 Share Posted August 6, 2022 Fusulinid is my best bet, too. ~ Isaac; www.isaactfm.com "Don't move!
