Fossil records
[edit]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]
The holotype is currently housed and displayed in Asti's Paleontological Museum.
Description
[edit]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]
