From the album: Fossil Amber and Copal: Worldwide Localities
8.0g prepared rough specimen displaying a partially polished face, measuring (mm) 50x22x14; this piece is a transverse section, and displays numerous layers or flow lines with sequences of micro bubbles as well as sediments. This material was recovered from the Malvern Clay Pits, east of Malvern, Arkansas. FTIR spectrum comparison of Claiborne amber to modern Shorea sp. resin points to the Dipterocarpaceae as a probable source for this middle Eocene-aged amber.© Kaegen Lau

So I'm having trouble identifying this fossil. It's from the bartonian of northern spain. I'm pretty sure it's some sort of brachiopod but I could be wrong. I don't know if any of you could help me with species category too (although I know it would be difficult considering how badly preserved it is)

4.1g rough specimen measuring (mm) 25x18x15. This is a section of a run, with successive layers grading from translucent to opaque; portions of the sand, clay, and lignitic matrix coats the exterior as depicted. This material was recovered from the Malvern Clay Pits, east of Malvern, Arkansas.

From the album: Barton Beds Hampshire UK Fish-Reptile-Mammal
Zygorhiza wanklyni (?) (Seeley 1876) Fossil whale material is not common from Barton two species are recorded. According to the British NHM this is " centrum of anterior lumber vertabra of archaeocete whale. Of the two genera recorded from the Barton Clay, it is closest to Zygorhiza. However, there are a few anomalous features, like the presence of 3 ventral ridges which might indicate that it is not this genus. The circular scar on the R-H ventral surface may represent where the gastropod (possibly Calyptraea) was attached as the vertabra lay on the sea floor" It was suggested at the time anyone working on fossil Whales in the US might be able to shed some more light on the vertabra. So if anyone can help I'd be gratefull. Further reading 'Notes on Fossil Whales from the Upper Eocene of Barton Hampshire by L. Beverly Halstead & Jennifer Middleton' PROC. GEOL. .
