Acrophyseter robustus by Bran-Artworks Acrophyseter robustus by Bran-Artworks

Más material sobre Acrophyseter incluyendo una especie más al género, Acrophyseter robustus que habito la costa peruana durante el Mioceno, hace unos 9 millones siendo la más antigua. La anatomía de estos cachalotes estaba adaptada a ejercer mordidas muy potentes como sugiere el nuevo material siendo depredadores ápices en su entorno.

More material on Acrophyseter including a new species to the genus, Acrophyseter robustus, that lived in the peruvian coast during the Miocene, around 9 million years ago being the oldest of the two, another posible species is also mentioned represented by a skull and mandibles. The anatomy of these stem spermwhales was adapted to excert powerful bites as the new material suggest, being apex predators of that time.

Ah, very nice, I knew you would do one! 

Man you have so many great ancient whales here, I wouldn't wonder if you would publish a book with them one day!

Thanks Joschua! actually thats my idea one day, :D l have slowly started to gather information on many of the ancient whales, it could take some years but is something i really want to do (although many of those cetaceans remains a very scrappy).

Great! I hope to be to publish one day a book about my dragons, but it's still a long way to go.

Good luck with that project =)

Indeed, problem is that I wrote the first chapter nearly to the end but lost the data then...

mas chacalotes! iba a decir ballena asesina, pero creo que eso entra en la característica de un mamífero marino cuyas extremidades aun son patas palmeadas (como un basilosaurus) esto ya es un cachalote bastante actual a pesar de ser antiguo.

Bueno, estos habitaron de entre 9 a 6 millones de años, tal vez un poco mas y ya tenían una forma familiar, es lo que se aprecia en los pocos esqueletos fósiles existentes de estos animales.
