Al Dente Posted November 6, 2018 Share Posted November 6, 2018 Nice one. It is from an odontocete. Boesse will be able to tell you more. @Boesse 5 Link to comment Share on other sites More sharing options...
Shellseeker Posted November 6, 2018 Share Posted November 6, 2018 It could be a river dolphin periotic like mine, or an ocean dolphin, or a porpoise. It would take someone like @Boesse to actually identify to a specific mammal.

ynot Posted November 7, 2018 Share Posted November 7, 2018 Nice find! Agree with a small cetatean. 1 Darwin said: " Man sprang from monkeys."

Boesse Posted November 12, 2018 Share Posted November 12, 2018 They're not from opposite sides. You've shown ventromedial and a ventrolateral picture, which gives us a nice idea of what the ventral side looks like. The dorsal side is also quite critical; this is the side with most of the 'holes'. On second thought: how many folks here would be interested in a brief guide to earbones? 6 Link to comment Share on other sites More sharing options...

That's a good model for future photography, Bobby, thank you.

Boesse Posted November 18, 2018 Share Posted November 18, 2018 1) @Harry Pristis - the periotic/petrosal I posted above is the holotype periotic of Brujadelphis, a late Miocene iniid from the Pisco Fm. of Peru. 2) @Vieira - apologies for not logging in in over a week - the first photo you posted is the dorsal side, so many thanks! The additional photos do help quite a bit. This specimen has some weird features typical of sperm whales, but appears to be a delphinoid periotic - Delphinoidea includes oceanic dolphins (Delphinidae), true porpoises (Phocoenidae), and the beluga/narwhal clade (Monodontidae) as well as some extinct forms (Kentriodontidae sensu stricto, Albireonidae). 3 Link to comment Share on other sites More sharing options...
