MelanieD Posted January 1 Share Posted January 1 Had a king tide combined with a storm front resulting some significant beach erosion and movement here in SoCal. Rockhounding today scored some pretty agates and this unique piece! It resembles others I’ve encountered on the beach (you might see one or more of them in previous posts). So, the question is…is this fossilized bone? Part of it looks like it, but another part doesn’t, so much… 1 Link to comment Share on other sites More sharing options...
Rockwood Posted January 1 Share Posted January 1 Yes, this is bone. The denser looking material is cortical bone, the more patterned area is cancellous bone. 1 1 Link to comment Share on other sites More sharing options...
MelanieD Posted January 1 Author Share Posted January 1 Awesome. How cool to get a good example of each!! It’s so worn, but it’s BIG. Hip? How do I determine what type of animal it’s from? Link to comment Share on other sites More sharing options...
MelanieD Posted January 1 Author Share Posted January 1 Also, it appears as though the bone has a quartz filled crack, which I also find interesting. Link to comment Share on other sites More sharing options...
Carl Posted January 2 Share Posted January 2 It'll likely be impossible to determine what kind of animal it came from but whale is most likely based on the size, texture, location, paleoenvironment, and fauna. 2 1 Link to comment Share on other sites More sharing options...

It likely is a silicate mineral filling a crack. Fossil bone that is durable often is silicified. In other instances, the bone has to be stabilized with a glue before it can be handled due to the presence of cracks. 1 Link to comment Share on other sites More sharing options...
