A friend of many years showed me fossils he had found on the beach in Estonia on the Bay of Finland. He asked me what they were. I had never seen anything like it from my area. I told him I would post it for him to see if anyone could ID it. I have no idea what Formation it is from, but it’s coming from the ocean. He said they’re all over the beach. Here is a group of them he collected on the beach. I’m mostly interested in the long fossils. I don’t have closer pics for the others. Side 1 Sude 2 End shot Thanks for any thoughts you may have.

Hello, found this in a cut limestone floor plate - I wonder what this might be. I am not a geology expert, I'm a medical researcher. The image is scanned, 10 cm real size. Regards, Alar Aints
