Re: [dinosaur] Size of new Spinosaurus specimen


No, it is nowhere near 15 m long. The specimen is incomplete (mid dorsals, pelvic girdle, hindlimbs, tail) and indicates an animal only about the size of the Baryonyx type specimen).

The 15 m size is the extrapolated size of a fully grown individual.

Good day,

I would like to ask if there is an information about the exact size of a new _S. aegyptiacus_ specimen from Morocco, described in 2014? AFAIK it should be a subadult individual that was about 15 meter long. How long/heavy could fully adult spinosaurus of these proportions grow? Thank you very much (also for previous replies)!

BTW, does anyone happen to have a pdf of the paper "Semiaquatic adaptations in a giant predatory dinosaur"? Thank you in advance, Tom
