I found this at Purse State Park recently. If it is a bone, does anyone have a guess as to what type of bone it is or what animal it's from? And, are there easy ways to tell fossil bones from modern bones? Thanks!

Looks like the distral end of a leg bone.

I think it is a small billfish vertebra. Compare it to the ones on elasmo.com>Lee Creek>Teleosts

I'm not sure exactly what it is but I think it's modern. From my experience at Maryland sites fossilized bone is usually black or brown. I'm going to Purse State Park for the first time Thursday or Friday. How is it?

@hemipristis - thanks for the billfish vert id. I looked on elasmo and couldn't say I saw the resemblance, but I really don't yet know anything about animal bones.

@mbroch - I've been to Purse twice now recently for a total of ~9.5 hours and ~500 teeth. Many teeth you'll find there are broken. There are probably several reasons for this, but one guess I have is that the majority of teeth are sand tigers and hence are somewhat more fragile than other varieties of teeth. I know you can find a lot of interesting teeth on the Potomac, and from what I've read on this site, at Purse specifically -- but I haven't found too many "rare" teeth yet from what I can tell -- only one nice P. rutoti. Aside from that, just some largish/complete sand tigers. There's definitely a nice stretch of shoreline to walk along, but in the afternoon it can get very hot with very little respite in the form of shade while you're collecting. Weather for later this week looks a bit cooler though, so you'll probably be fine. Good luck!

@pknut777 Thanks for the advice! I'm going tomorrow so hopefully I'll find something.

Happy hunting
