Another similar talk of the same author, earlier (2010), with some complementary information :

As for Carcharocles, officially it is widely called as such, though in Europe, it seems to have been renamed Megaselachus megalodon, as well for the other Carcharocles genus.


I am pretty sure since a while that orcas may not have preyed on Megs, at first indeed because the contemporary species, O.citonniensis, was much smaller but also that because Orcas only prey rarely on large whales, mainly juvenile and the battle takes hours. During the famous attack facing 29 Orcas against a 18 m Blue Whale, it took 5 hours of struggle for severly injure the whale.
As said above, no Orcas attack Bull Sperm Whale in Nature. So, I m highly skeptical that even modern Orcas would have tried to engage a full grown Carcharocles megalodon which is know for attack baleen and sperm whales during its time.

Fair enough, the Orcas and the smaller predatory sharks were more adapted to the new global situation in oceans.

Don´t see why not... I've seen fossils much rarer and scientifically valuable being sold on the web...

They're pretty common Z, so yea you would see them on ebay. I've seen a genuine mammoth skull and tusks on the bay. eBay can be quite a good place to get fossils. You have to be careful of course. EG 90% of the so called cave bear fossils are of more modern bear types.

Megaselachus megalodon... I'm not sure about this name although it is a little bit more epic than "Carcharocles"... but nothing like the sound of the old Carcharodon megalodon

[Galvasean]

Was Megaselachus not abandoned as a genus in the late 60s?

Not sure exactly when Megaselachus went out of vogue but it was what is now called Carcharocles megalodon

Hope that helps.
