Fossil ID

[Bgerwick]

Does anyone have any idea what type of dinosaur bone this may be? Its extremely heavy and about 40 inches or more long.I. was thinking it may be a humorous bone (upper arm)but I really have no clue. Any knowledge would be greatly appreciated

Hello

If you can put some more pictures of it.

I don't see any bone structure there...

For me it is only a sugestive rock...

Could be a concretion... but from that photo, I don't see it as being a fossil.

Welcome to the Forum.

Rotated and brightened the pic.

Unfortunately, there is no real bone shape to this, and no bone texture as well.

This appears to be a large piece of weathered limestone.

Yes, weathered limestone. Water movement can cause these odd shapes to erode out. This normally happens with many shapes being produced, and sometimes making "bone piles" of streamlined shaped. Your eye can pick out many different shapes from the random shapes.

I once built a deer out of weathered limestone. It was shockingly convincing from 20 feet away.

I have more pictures make take a min. To post all of the but this was found way far in the ground 20 to 30 feet. This on of my many fossils though its the biggest one I have. Doesnt the age of fossils determine the difference in preservation/appearance? Im new to all the fossil facts. I just collect them and have since I was a kid..

The pictures with the blue towel are taken on a skate board so you may see the yellow wheels or the actual plastic board underneath the bone or the object in question

2nd pic is the oth side of it

I know it looks like it has the shape of a bone, but this appears to be one of the large, fossil burrows that are commonly found in a couple of North Texas geologic formations. The sediment that found its way into these "holes" is often harder than the surrounding rock. They are usually exposed by erosion.

Fossil bone has distinct, identifiable characteristics — no matter what the age — that go beyond just the shape. You should fossils to be able to find other fossils near where you found this burrow.

Doesnt the age of fossils determine the difference in preservation/appearance?

No it does not have anything to do with state of preservation or the appearance- other than what it is. You will not find a bone in the cambrian, nor will You find a trilobite in the miocene.

There are a lot of combining events that can affect the way a fossil is preserved and how it appears. How long was it exposed before burial, what minerals are in the soil, how much pressure was applied by overlaying roch and how long was it exposed before it was found are just a few.

Also, I agree with JohnJ about what You have found.

maybe a burrow

maybe a burrow

If it's a burrow, it was made by a decapod that goes to 11. :-)

Hey Craig, for a wild trace fossil, check out the spiral burrow left by the ancient beaver called paleocaster.

That is crazy! Amazing how he gets it to be so symmetrical.

That is because one leg is shorter than the others.
