Barinasuchus

Barinasuchus is an extinct genus of sebecid mesoeucrocodylian. It lived in Argentina, Peru, and Venezuela between the middle Eocene and the Late Miocene, ~42–11.6 Ma. Described in 2007, based on a severely damaged specimen from which only a snout tip was recovered, Barinasuchus is known from a single species, B. arveloi, named after Alberto Arvelo Torrealba, a local educator and poet.

3 occurrences of Barinasuchus on record, most of them in the Miocene. Bar height is expected occurrences, not a count: each fossil is spread across the span it is dated to, so a tall narrow bar means tight dating and a low wide one means loose.

When

3 occurrences

These are dates about fossils, not the animal: the record can only begin after it arose and end before it died out, so either end may reach further. Shares are expected occurrences: a fossil dated to a span is counted partly in each period it straddles. More on what this infers.

The Paleobiology Database records 3 sites for Barinasuchus, and this reads all of them. The number is how many of those sites it was catalogued from too.

This is not a list of everything alive at the time. It is only what has come out of the same ground as this animal and been written down.

Each of the 3 occurrences read was entered from one of these publications, ordered by how many each accounts for. This is not a search for papers mentioning the name. Each entry links to the Paleobiology Database's own record for the work.
