Paleonet: Unknown fossils and some help?

[Michael Howe - BGS]

Hi Russell,

The third is an obliquely preserved graptolite. The dimensions (Dorso-Ventral Width = 3mm) look about right, but the thecae are at an angle and difficult to visualise. They appear to be small lobes.
The second looks like a member of the echinoderms.
The first is really odd…….

Regards,

Mike

Hi PaleoNet People!

So I have been having a look through the AMNH collection and came across three fossils that have very limited metadata but look really interesting. I was hoping someone out there might be able to help!

The first is from Costa Rica, age known
The second is from the Hamilton Group, ??Devonian
The third is from the Clinton Shale, Silurian.

Any help would be greatly appreciated, and may lead to some interesting collaborations!

Cheers!

Russell Bicknell.
