Nj Bone And Tooth Id Help


ChesterCounntyPA

Recommended Posts

From a Monmouth County creek. The bone feels heavy and solid, although it is hollow. There is no odor when a flame is applied (I used a lighter on the end). The bone is right side up in the first 3 photos, and the last picture shows the reverse side,which is much flatter. The unbroken end is knobby. Are there any other tips for testing or identifying it?

The tooth also has a heavy feel to it. It has a slight edge on the outer curve, right near at the top where there is still enamel. I can also feel an slight edge or ridge on the inside of the curve, although off to the side a bit. The flash in the pictures 1-3 and 5 make it look lighter in color than it is.

Thanks!!!

It looks like a Whale tooth to me. Im not sure about the bone frag.

The bone appears to be a distal radius . . . perhaps a very-worn example from a horse.

The tooth is reptilian . . . perhaps from a mosasaur or a crocodilian.

Now that Harry suggested Reptile i do have to agree given the round shape and cavity of the root.

The partial radius (lower front leg bone) is from a deer and much like other modern examples I've found at Big Brook. The discoloration doesn't mean much for determining age. Everything that ends up in Monmouth County streams will be discolored from the rich organic and mineral content of the mud and water.

Wow, thanks for sharing your knowledge! Your explanations are really helpful.

So, a partial lower front deer leg bone of undetermined (but not ancient) age. The color is not indicative of advanced age, nor is passing the burn test.

Thanks also for greatly narrowing down the tooth possibilities as reptilian. The base definitely looks more round than oval to me, for whatever that's worth!!

a dead deer bone can be colored like this after time in the brook but it does look mineralized to me. Looking a certain way isn't necessarily a definite thing though of course. A dead deer bone stinks when you burn it and usually has a dull tap when tapped on ones teeth compared to a mineralized bone. Yes, a Pleistocene bone could be just bone and probably a fairly modern bone could be mineralized. This being said I wouldn't discard this as modern trash.

Thanks again Plax, Rich and jpevahouse. The "tooth tap" (I'm that curious) seems higher pitched rather than pure "thunk," but I have no comparators.

And, eboe, Harry and "fossilized6s, any thoughts on what type of croc? The tooth is a decent size, about an inch long. Are you thinking largish Thoracosaurus or maybe....Deinosuchus?

if the hole at the base of the tooth is roundish and has concentric rings I 'd say croc. If elliptical it could be Mosasaur (but not certainly)

The tooth looks like mosasaur. the croc teeth I've found were more hollow. ....and smaller...

Thanks! Here are more pictures. The inside is indented, with a small center hole, about 1/8" deep at the most. It looks solid beyond that point. The tooth is heavy. There seems to be a ring around the inside edge but I can't discern other distinctive rings.

is there any carinae? crocs lack this feature here.

What do you mean when you say that crocodilian teeth lack carinae here? Do you mean in New York? . . . On this forum? Where's the here of your assertion?

I ask because here in Florida, crocodilian teeth display carinae . . . even the recent 'gators have teeth with carinae. See the 'gator carina in the first image.

There are (non-serrated) carinae, one is plainly visible on the back of the tooth (photos 1 and 2) and there is one that is less prominent on the side (picture 3, with arrow).
