Barinasuchus (meaning "Barinas crocodile," in reference to where the type material was found) is an extinct genus of sebecid mesoeucrocodylian. Its fossils have been found in middle Eocene-age rocks of the Divisadero Largo Formation of Argentina, middle Miocene-age rocks of the Ipururo Formation of Peru, and middle Miocene-age rocks of the Parángula Formation of Venezuela.[1]

Description

The holotype comes from Parángula Formation rocks in Barinas and consists of an incomplete articulated skull and lower jaw. Like all other sebecosuchians, it was a terrestrial carnivore with ziphodont teeth, like a theropod dinosaur. This made it a formidable predator.

Barinasuchus is the largest sebecosuchian (preserved part of the type specimen skull is 700 millimetres (28 in) long), and is the first sebecosuchian known from Venezuela. Fossils from Peru previously identified as Sebecus cf. huilensis have been assigned to the type species, B. arveloi.

Barinasuchus was described in 2007 by Alfredo Paolillo and Omar Linares.[2]

gollark: $30 for a cluster *and* peripherals? No.

gollark: Again, less so in perf/$.

gollark: Like I said, it isn't good for anything but learning clustering, since most stuff will not actually conveniently parallelize across devices and x86 systems offer more perf/$.

gollark: Clustered RPis aren't actually that good for much beyond cheaply learning clustering tech.

gollark: They're pretty cool, although not really optimal for more electronicsy things since the SoC is apparently for TV boxes.
