GallinaPinta Posted December 15, 2019 Share Posted December 15, 2019 I found this bone in the san sebastian limestone, in Puerto Rico. I always find interesting fossils there, but this is the first bone I collect. There have been skeletons of extinct sirenia found in this exact same place, so maybe it could actually a fossilized bone from an extinct species. I have no clue when it comes to bones though, so an expert is highly apreciated. Link to comment Share on other sites More sharing options...

Rockwood Posted December 15, 2019 Share Posted December 15, 2019 This is from a terrestrial animal, likely a mammal. Link to comment Share on other sites More sharing options...

Plax Posted December 17, 2019 Share Posted December 17, 2019 there are often modern to Pleistocene solution cavities in the top of earlier limestone beds that make effective pitfall traps or carnivore lairs. Your bone could be one of these fossils despite its modern appearance. Modern bones exposed at the surface deteriorate with the interior marrow and porous portion rotting away first. This doesn't mean that older bones of mammals for instance can't be preserved this way. Cave bones are often hollow. 3 Link to comment Share on other sites More sharing options...

MrR Posted December 18, 2019 Share Posted December 18, 2019 Have you used your scale lighter in order to see how it smells when it has a flame put to it? You might get something out of this post from an earlier year. The odor of the not necessarily blue flame. 1 Link to comment Share on other sites More sharing options...

If the dogs eat it, it's probably modern, if their teeth break, it's likely a fossil. Life's Good! Tortoise Friend. Link to comment Share on other sites More sharing options...

That is, unless they have a habit of chewing rocks. 1 Link to comment Share on other sites More sharing options...

One of my girls bought me a clam bivalve to play with. Anything that smells like the river, they will collect lol 1 Link to comment Share on other sites More sharing options...
Plax Posted December 18, 2019 Share Posted December 18, 2019 Late Pleistocene bones may still be bone especially in cave deposits. Of course there are numerous bones in the arctic of Pleistocene megafauna even with flesh and hair. Mineralization doesn't make a fossil. 2 Link to comment Share on other sites More sharing options...
