When I first saw this tooth, I was thinking Allodesmus, maybe seal. But then I noted the hollow root. Certainly not croc/gator, so whale ? Do Dolphins have hollow roots? The ones I have found have closed roots. If whale or dolphin, which one? Tooth is about 2.6 inches long. Usual suspects: @Boesse, @ynot @siteseer Comments on open versus closed roots in marine mammals appreciated.

I have recently been blessed to acquire some excellent Shark Tooth Hill (STH) marine mammal teeth. Not totally happy on not knowing what exactly I have, I am reaching out to STH experts to enhance my knowledge and understanding (but mostly to identify these fossil). One TFF member who has extensive knowledge of STH is @ynot because he sent me matrix and micros from STH. So, Tony please invite other STH enthusiasts to assist here. After spending time looking at the Pinnipeds: Seals, Sea Lions, and Walruses teeth, both fossil and modern, I am confused about a lot of things: Here is one of my teeth to ID: Seems easy, 25 mm Seal molar.... or is it ? On a $$ForSale website , I see this STH Sea Lion tooth -- molar ? that at 1.25 inches looks the same.. So do Seals and Sea Lions have the same/similar teeth only larger? Here are 3 teeth where I would be pleased with confirmation, identification, alternate possibilities. Is this incisor an incisor or a molar ? Is it the approximate size of a seal incisor? A harbor seal's incisors for comparison. Here are the canines of a Weddell Seal... At 38 mm, Can this canine be Seal, maybe lower jaw.... Lots of questions, Hopefully will trigger a good discussion..
