minnbuckeye Posted February 28, 2020 Share Posted February 28, 2020 I missed these few fossils when trying to ID some unknowns from the Peace River a few days ago. 1. This one really intrigues me. Hopefully not just coral . 2. Very pitted. 3. I am a little unsure of these teeth. They just had a different appearance from the other teeth I could ID with confidence. I will repost a few from an earlier try for identification. 4. Bone of some kind 5. Broken tooth? Of what? A ridge down the length of the tooth visible in the first picture. Break visible in the second pic. Link to comment Share on other sites More sharing options...

It looks like sediment that once covered a coral colony making an impression of the corallites. 2 Link to comment Share on other sites More sharing options...

Just in case it was something different, I hated to pitch it. Link to comment Share on other sites More sharing options...
Spoons Posted February 29, 2020 Share Posted February 29, 2020 Are these tooth sockets? 1 Link to comment Share on other sites More sharing options...
ClearLake Posted February 29, 2020 Share Posted February 29, 2020 To me, your bone #4 looks like the end of a long pastern (proximal phalanx) bone of a horse or horse like animal (a perissodactyl for certain). I say this because the divot in the center with the depressions on each side is very characteristic of the joint with the end of the cannon bone. It looks like an epiphysis but I’m not sure those bones have that, at least in modern horses. See the picture below of a modern horse phalanx as an example of what I think your bone is (yours is just the end, not the whole bone). 1 Link to comment Share on other sites More sharing options...

Harry Pristis Posted February 29, 2020 Share Posted February 29, 2020 The first object reminds me of shark tesserae, even though the florettes do not adjoin one another as in the illustration. The fourth object IS an epiphysis from a horse toe. See the x-ray below. 3 http://pristis.wix.com/the-demijohn-page What seest thou else In the dark backward and abysm of time? ---Shakespeare, The Tempest Link to comment Share on other sites More sharing options...

I looked it over and can't decide between the two IDs. Though coral is always the "common" find, could Harry Pristis be correct? Other opinions??? Any one else found tesserae in the Peace River Watershed? For those who do not know what tesserae are, here is what I found. Crystals would explain why tesserae could be preserved. In certain locations where strength is particularly important - such as the jaws and parts of the backbone - shark cartilage is fortified with tiny, hexagonal crystals of calcium salts called "tesserae". fromhttp://www.elasmo-research.org/ Link to comment Share on other sites More sharing options...

I was thinking some type of scute or maybe bone that has worm borings. But that was a good thought! Link to comment Share on other sites More sharing options...

For all of the horse experts, would this be from a juvenile? I assume the epiphysis would be strongly attached to the diaphysis in an adult.
