Fossil records

This genus is known in the fossil records from the late Zanclean–early Piacenzian (Pliocene) (age range: from 3.81 to 3.19 million years ago). Fossils are found in the marine strata of Piedmont (northern Italy).[1][2]

Description

This genus is characterized by a condylobasal length reaching about 550 millimetres (22 in), by a long and narrow rostrum and by a wide premaxillae at the middle of rostrum. It shows an extreme posterior widening of the dorsal opening of the mesorostral canal.[2][3][4]

gollark: According to Wikipedia he's been with Tesla from a year after they started and ran it since 2008, so I feel like he deserves much of the credit for that.
gollark: It's ridiculous to complain that he doesn't know much about rocketry and stuff himself and (THE HORROR) hired competent people who do, and managed to improve the state of space travel a lot.
gollark: I'm not sure what you mean by "apartheid profiting", but generally that seems pretty stupid.
gollark: Unless they have a warrant, you can apparently just tell them to go away and they can't do anything except try and get one based on seeing TV through your windows or something.
gollark: But the enforcement of it is even weirder than that:- there are "TV detector vans". The BBC refuses to explain how they actually work in much detail. With modern TVs I don't think this is actually possible, and they probably can't detect iPlayer use, unless you're stupid enough to sign up with your postcode (they started requiring accounts some years ago).- enforcement is apparently done by some organization with almost no actual legal power (they can visit you and complain, but not *do* anything without a search warrant, which is hard to get)- so they make up for it by sending threatening and misleading letters to try and get people to pay money
