When I saw a fish hypural for the first time, I didn't think it was real. But, now, these obscure bones are better known. Who here has a fish hypural to show us? Here's one: "The bony structure (often fan-shaped) that chiefly is composed of the expanded, flattened and partially fused hemal spines (ventral extensions of the vertebrae), and that supports the caudal-fin rays in most bony fishes; when counting vertebrae, this composite element is treated as a single vertebra and included in the count. Amia has 10 hypurals, Salmo 7 but in most teleosts the number is reduced or fused into a single structure, a urostyle."

Bony fish specimens from the Eocene of Virginia
MarcoSr posted a topic in Partners in Paleontology - Member Contributions to Science
A number of Eocene bony fish specimens from Virginia that I collected and donated to the Smithsonian are described in an article by Dr. Robert E. Weems “ADDITIONS TO THE BONY FISH FAUNA FROM THE EARLY EOCENE NANJEMOY FORMATION OF MARYLAND AND VIRGINIA (U.S.A)” published in The Mosasaur Volume XI June 2020. I collected and donated the following specimens shown in the below figures: 4D thru 4F: 5A, 5C, 5D, 5E: 6A, 6B, 6G, 6H : 7B: 8A, 8B: Marco Sr.- 17 replies

Hi, everyone, it's been a minute -- I hope y'all are well and that you and your families are healthy and safe. I'm required to say "y'all" since we moved to New Orleans last summer. Fantastic city, great people, but I won't be peeking in the Chesapeake or anyplace else on the East Coast again any time soon. Then, *this* all happened. During this lockdown, it occurred to me that I could finally get around to trying to identify some of the material I've had sitting in boxes for years (and I'll post a few others). But what do I find when I log onto the FF after ages? A positive gaggle of Mazon ID posts. Love it! I collected this little fish in 2010 from the South Unit at Mazonia-Braidwood. He measures a whopping 13mm from nose to tail. I've been poking around on the web but I'm having a hard time with the ID. It looks like he has two spiky fins sticking up from just behind his head (they're clearest in the last photo). My brain itches with knowing that I've seen this guy someplace before, but I just can't find him again. Thoughts? Thanks...y'all.

Hello Everyone, I had the honor of being invited by @markmg to a trip down into essentially ... a big hole in the ground. Woo Hoo !! A rather large gravel/sand pit that is being mined to 50-60ft ? We were not quite sure but hopefully at least as deep as the dredging that happens on the river. You know .. a play date ! .. haha Well, having just rained out my river trip on Friday I came prepared to slog through some mud. Let's just say it was lucky we didn't have a The Princess Bride (1987) moment because the water made the sand and mud a bit soft in some spots. The open pit has to be constantly pumped out or it would fill up with water and you'd have a nice deep pond ... not so good for a gravel business. Mark had been down in the pit on several occasions and asked that I join him and see if I couldn't help him find anything ... Mark was being brutally teased having previously come out and found - ON THE RAMP- a partial meg tooth. Well, we didn't find any mega-sharks down in the pit, but after exploring for about 90 minutes, the first small hints of the phosphate pebbles we were looking for started showing up. They were washing out of a layer sitting just above an impermeable formation of red compacted clay with shell impressions. Unfortunately the preservation was poor. And very crumbly .. I'm assuming these first finds had been sitting out too long and they were returning to the ground. They were encrusted with precipitated minerals and were delicate. The first hints that maaaaaybe this wasn't a dry hole ?? Some of the encrusted bone that didn't crumble to dust ....

I have a pretty extensive collection of shark, ray, fish and other micros from sites all over the US, Europe, North Africa and Australia. You can see a very small part of my collection in my TFF posts at the below links. As I add new posts to TFF I'll update this list.

Hi everyone, I was wondering how one would distinguish the armor skull plates of a gar with some of the osteoderms found on sturgeon. I have definitely found the former but cannot be certain if I've found the prior. From looking at some pictures online I see similarity between the two and wondered if I had any in my collection and if I could properly identify a fossil as sturgeon as opposed to gar.

Leptolepis coryphaenoides from the "Unterer Stein" in Holzmaden. Its a rare find but the most common specimen in this area. The fish is about 7 cm long.
