Rock-Guy-17 Posted September 14, 2021 Share Posted September 14, 2021 Hello again, I have some more photographs of fossil specimens that I am unsure about or looking to confirm. Appreciate the help. 1. Devonian, Genesee Formation from around Dansville, NY. Agonatite? Gastropod? 2. Also Devonian, Onondaga Formation I believe, Erie Co.. I am not great at trace classification ID beyond that it looks to be a trace burrow 3. Devonian Moscow Fm., Erie Co. The little fossils on the left side of image? Can't find any sources on these. Neat trilobite eye in the rock. 4. Rugose Coral, Devonian Livingston Co. What is the fossil attached to the coral body? 5. Irondequoit Formation I believe. Definitely from Lockport, NY. These Bryozoa or some type of coral? Link to comment Share on other sites More sharing options...
historianmichael Posted September 14, 2021 Share Posted September 14, 2021 I can confirm that #5 are bryozoa from the Middle Silurian Rochester Shale. As for the others, it may help to see photos from different angles. It is tough to make out what exactly you are interested in. 2 Follow me on Instagram (@fossil_mike) to check out my personal collection of fossils collected and acquired over more than 15 years of fossil hunting!

daves64 Posted September 14, 2021 Share Posted September 14, 2021 #4 might be a tiny crinoid holdfast on the coral. 2 Accomplishing the impossible means only that the boss will add it to your regular duties. Link to comment Share on other sites More sharing options...
Rockwood Posted September 14, 2021 Share Posted September 14, 2021 1-Ya probably. 2-Oops. Nope. Heliolitid coral. 3-Serpulid worms. Most likely. 4-Yes. Crinoid holdfast. Link to comment Share on other sites More sharing options...

I think Tim understands that the nature of microconchids uncertain. I was concerned that it could be misunderstood however. Link to comment Share on other sites More sharing options...

Like Spirorbis. 9 hours ago, Rockwood said: . 3-Serpulid worms. I think Spirorbis doesn't appear until the Miocene It is a serpulid polychaete annelid, not a micoconchid. Serpulids don't appear until the Permian. Microconchids are thought to belong to the lophophorata or maybe the lophotrochozoa and probably to the Tentaculita. As I understand it, and someone please correct me if I'm out of date with the info as i find all this fascinating, the majority of 'serpulids' found as fossils before the Middle Jurassic are now thought to be microconchids.

FossilDAWG Posted September 14, 2021 Share Posted September 14, 2021 Tidgy's Dad is correct about the time frame of microconchids vs Spirorbis. Although the two are very similar in appearance, and both are/were epifauna on shells or other firm substrates (even "seaweed"), they differ in their shell microstructure. Paleozoic "spirobid"-looking fossils were not recognized as being different from modern Spirorbis until they were thin sectioned and the shell structure (such as number and composition of layers) was studied in detail.

Rock-Guy-17 Posted September 14, 2021 Author Share Posted September 14, 2021 Sorry about the scale of the pictures, I took these a while ago and labeled them on my computer for ID purposes so I will try to include a scale measurement for now on. Thank you for the help for ID: 1. appears that folks agree that it is agonatite? 4. Crinoid holdfast 5. Rochester Fm. Bryozoa (anyone know species name?). Lockport is a great spot to look for these fossils Here are some (hopefully) better pictures of 2 and 3 2. Syringopora coral from Don 3. These squiggly circle things.
