Vopros Posted March 10, 2023 Share Posted March 10, 2023 Hi here is a rock from a beach in California. As you see it has lots of fossil shells and something else that is much bigger than shells. What is this something else? It is a microscopic image. Link to comment Share on other sites More sharing options...
Doctor Mud Posted March 10, 2023 Share Posted March 10, 2023 (edited) Can you tell us the scale for the field of view? I presume something like a few cm or an inch across? looks like your “shells” are benthic foraminifera a type of microfossil and the large object looks an element from a fish skull to me. Possibly a pre-maxilla near the snout? @Fossildude19 Edited March 10, 2023 by Doctor Mud 1 Link to comment Share on other sites More sharing options...

Doctor Mud Posted March 10, 2023 Share Posted March 10, 2023 The new thing is a sea urchin or echinoderm. The first thing definitely looks like a bone from a fish skull. There are many types of fish all with weird and wonderful skull arrangements. Then there are many bones in the skull, but that does remind me of fomenting like a pre-maxilla which is a bone from the snout. There are a few fish experts on here and I invited them to come have a look too. Link to comment Share on other sites More sharing options...
patelinho7 Posted March 10, 2023 Share Posted March 10, 2023 I also see a premaxilla but what are the features jutting out from the left side? 9 minutes ago, Doctor Mud said: The new thing is a sea urchin or echinoderm.

Vopros Posted March 10, 2023 Author Share Posted March 10, 2023 (edited) Thank you, all! Here is a higher resolution of the “fish?”. I combined a few images together. I believe I could see rims on the “bones”. Will fish bones have rims? Edited March 10, 2023 by Vopros Link to comment Share on other sites More sharing options...
Fossildude19 Posted March 10, 2023 Share Posted March 10, 2023 Fish Premaxilla would be my guess as well. No clue any further than that. Lots of small fishes present in the Miocene coastal deposits.
