Mango Posted August 31, 2010 Share Posted August 31, 2010 What creature was attached to these bones that made these markings? There are more of the same marks on the other sides of the bones. None of the marks seem to overlap. Marking size ranges from 3/4"-1" long x 1/2"-3/4" wide. Found these digging in SWFL. Bone fragments are the same as I find in the Peace River which I call dugong ribs. These are the first I have found with these markings. Worm bore holes, I have lots of. Thank you.

Tracer Jr. Posted October 24, 2010 Share Posted October 24, 2010 could some of them possibly be ivory or tooth fragments? Link to comment Share on other sites More sharing options...
bear-dog Posted October 24, 2010 Share Posted October 24, 2010 could some of them possibly be ivory or tooth fragments? No usually on bone frags.there.Most suggest worm bore holes. Bear-dog. Link to comment Share on other sites More sharing options...
tracer Posted October 24, 2010 Share Posted October 24, 2010 are you talking about those round indentation things? could something like sea anemones or some other "attaching" critter (limpets, remoras?) exude some sort of enzymaticallyacidificalcifileachitaciousness that would do that as a byproduct of they're hanging around being the benthic equivalent of couch potatoes? p.s. - i think i took great license in expanding the meaning of the word "benthic", but oh well, my cat gave me permission to. <==he also said i could end that sentence with a proposition, so do you wanna, huh? whut? i'm looking for a partner to help finance my explorations, is all... wait, snarge, i can't say that here! this isn't the member trades & sales forum! disregard, disregard, hatten down the batches! submerging, NOW!!! <tracer heads for benthic climes at warp factor slicks, mr. auspock.> Link to comment Share on other sites More sharing options...
dhk Posted October 25, 2010 Share Posted October 25, 2010 I'm going with the worm bore holes idea. Very nice bones though Link to comment Share on other sites More sharing options...

Boesse Posted October 26, 2010 Share Posted October 26, 2010 Sorry, those appear to be phosphate nodules. Those also do not appear to be any sort of markings, borings, or tooth marks - it appears to just be the surficial texture of the nodules.

Bobby Upon your suggestion, I more closely examined all of the pieces. I don't know what phosphate nodules look like, so I did a quick search for images. Couldn't find anything that resembled these pieces. I am still convinced they are bone. One of the pieces shows better signs of being bone than the others. There is visible grain on the side, and some porosity at the end. Very much resembles bone fragments that were found next to them. The markings make me picture a creature like a limpet attached to it. Might have been a lower profile creature, as some of the pieces have the marking on all sides.

Mango Posted October 27, 2010 Author Share Posted October 27, 2010 This piece is pyramid shaped with a single mark on all sides of it. Thanks for the replies and ideas. I had given up on these, and tossed them into my low grade bone/rock box, which is to eventually end up in a rock garden. You have to save a while to have a rock garden in FL.

Boesse Posted October 27, 2010 Share Posted October 27, 2010 Well ######, you should have posted those pictures first! That's bone alright, except they're all highly abraded phosphatized bone pebbles. You can't see any of that bone texture in the first photograph at all.

This is not the first case of my photos not being worth 1000 words. So what sucked on these bones before they became phospatized?

Boesse Posted October 28, 2010 Share Posted October 28, 2010 If anything modified the surface of these bones prior to phosphatization, it's been destroyed by now - these bone fragments are totally abraded pebbles by now. Bobby Link to comment Share on other sites More sharing options...
