Tooth for ID. Basilosaurus?

Recommended Posts

I saw this tooth on an auction site for relatively cheap.

Do you know what it is from? The tooth is from Dakhla, near Morocco.

I was thinking Basilosaurus.Any thoughts? Worth considering?

What do you think?

Looks to me like a Basilosaurus, their fossils do come from that area.

Whichever ancient whale it comes from, i have seen far better specimens than this from that area. 

I would pass.

The species Basilosaurus has not been reported from the Western Sahara area.

Wait, so does that mean all identifications of Basilosaurus isis are now invalid if it came from Dakhla?

I will leave that to experts like Boesse to address but in the attached post from above he stated that was from Egypt and US and Eocetus schweinfurthi - is known from Western Sahara as well as the basilosaurid Platyosphys and possibly the protocetid Pappocetus

Not quite true - Zouhri et al. (2014) reported Basilosaurus isis from the Samlat Formation of Ad-Dakhla on the basis of a vertebral column. Apologies for being somewhat unclear before; there is a late Eocene assemblage (ad-Dakhla) and a somewhat older late middle Eocene locality with more completely preserved material (Gueran) that lacks Basilosaurus (which is what I was referring to in the linked post). I am not certain that Basilosaurus has been dentally diagnosed before, but if it is substantially larger than the lower molars of Dorudon atrox than it is likely going to be Basilosaurus (since Cynthiacetus is only known from new world localities).

No, they have discovered they were incorrect about the time period at ad dakhla. There are actually at least 2 basilosaurus found there. Isis, and another Ive only seen mentioned in general, as basilosauride, so I guess they haven't settled on the species yet.
