Stan Simpson Posted October 31, 2016 Share Posted October 31, 2016 This fossil is different than any of the pieces found to date. It seems more porous than previous fossils. It has holes as shown with some running all the way through the fossil. It comes from the same dredge operation near Houston Texas as previous pieces. Thanks for your help.

caldigger Posted November 1, 2016 Share Posted November 1, 2016 It's the inner marrow area of a bone that has had the outer surface worn off. Not sure if you will be able to get more of an ID. Link to comment Share on other sites More sharing options...
fifbrindacier Posted November 1, 2016 Share Posted November 1, 2016 It seems to be the spongious part of a bone, and some of the holes you see are for the passage of blood vessels and nerves.

Rockwood Posted November 1, 2016 Share Posted November 1, 2016 With a vessel the size of your thumb I think it's safe to say it was rather large. Link to comment Share on other sites More sharing options...
lissa318 Posted November 3, 2016 Share Posted November 3, 2016 If from a marine environment it is possible that some of the larger holes are from clams. They are pretty good at boring pretty round holes through almost anything that has been in the water long enough! Link to comment Share on other sites More sharing options...
Shamalama Posted November 4, 2016 Share Posted November 4, 2016 Might have been part of a whale at some point since the remnant is so large. -Dave __________________________________________________ Geologists on the whole are inconsistent drivers. When a roadcut presents itself, they tend to lurch and weave. To them, the roadcut is a portal, a fragment of a regional story, a proscenium arch that leads their imaginations into the earth and through the surrounding terrain. - John McPheeIf I'm going to drive safely, I can't do geology. - John McPheeCheck out my Blog for more fossils I've found: http://viewsofthemahantango.blogspot.com/ Link to comment Share on other sites More sharing options...
