Isurus desori?

[B1978]

I have seen a lot of isurus retroflexus, but this one looks more barrel shaped where the enamel meets the root.

Could it be I. oxyrhinchus? [edit: I'm not sure how to distinguish desori and oxyrhinchus, hopefully others can weigh in on that]

I think some consider desori and oxyrinchus to be the same thing.

Thank you. I was unaware of I. Oxyrhinchus.

I agree after reading a source that referred to the two species as “synonymous”.
