yzhang Posted September 14, 2014 Share Posted September 14, 2014 Hello, here is a piece of bone I found today. At the first look it seems just a piece of shell but after clean up it show a clear bone structure, so I now think it seems a piece of bone... It's about 1.5''*1.2*1 in dimension and has a quite unusual shape. I have no idea about what this could be, neither did those in the Aurora fossil museum today. But we thought a part of the ear bone might be a possible answer... Thanks!! --YZ Link to comment Share on other sites More sharing options...

Boesse Posted September 14, 2014 Share Posted September 14, 2014 I think it's a fragmented and abraded odontocete squamosal. Link to comment Share on other sites More sharing options...

Boesse Posted September 15, 2014 Share Posted September 15, 2014 Most cetacean squamosals do, if you look at a disarticulated skull it's pretty apparent. The corrugated suture is probably the parieto-squamosal suture. I'd recommend checking out Mead and Fordyce (2009): https://repository.si.edu/handle/10088/8298 1 Link to comment Share on other sites More sharing options...

It makes much more sense to me now best, --YZ Link to comment Share on other sites More sharing options...
