Phrynops

Phrynops is a genus of sidenecked turtles of the family Chelidae. Sometimes called the bearded toadheads, this genus inhabits waterways of South America, where it is widely distributed: they are found in the Orinoco to Amazon basin and São Francisco to Paraná and adjacent river basins of Colombia, Venezuela, the Guianas, Brazil, Paraguay, Uruguay and northeastern Argentina.

13 occurrences of Phrynops on record, most of them in the Miocene. The Paleobiology Database records this as a living group. 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

13 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.

182 taxa

The Paleobiology Database records 7 sites for Phrynops, and this reads all of them. The number is how many of those sites it was catalogued from too. The 24 sharing the most are listed.

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.

Entered from

11 references

Each of the 13 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. Entries link to doi.org where the Paleobiology Database holds an identifier, and to its own record where it does not. Relayed as the Paleobiology Database holds them, not checked against what they resolve to.
