Doradidae

The Doradidae are a family of catfishes also known as thorny catfishes, raphael catfishes or talking catfishes. These fish are native to South America, occurring in most river basins, though they are absent from the Pacific Coast drainages and from coastal drainages south of the Río de la Plata. About 70% of the valid species occur in the Amazon basin; the Orinoco basin harbors about 22 species and ranks second in species richness. Conversely, only two species of doradids have been described from Brazilian eastern coastal basins: Wertheimeria maculata from the Jequitinhonha and Pardo rivers and Kalyptodoras bahiensis from the Paraguaçu River.

8 occurrences of Doradidae on record, most of them in the Miocene. The Paleobiology Database records this as a living group, and the chart stops with its fossils rather than at the present. 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

8 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.

223 taxa

The Paleobiology Database records 7 sites for Doradidae, 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

6 references

Each of the 8 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.
