Pseudobagrus sp.

Pseudobagrus is a genus of bagrid catfishes that inhabit streams and rivers throughout East Asia. These species fossils were found in Japan. The two Coreobagrus species, C. brevicorpus and C. ichikiwai, are both treated in some recent literature as valid in Pseudobagrus. It has been noted that Pelteobagrus may not be monophyletic if species placed in Pseudobagrus and Coreobagrus were excluded. The taxonomy of this genus is unclear and many authorities treat it as a junior synonym of Tachysurus.

3 occurrences of Pseudobagrus sp. 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 Pseudobagrus sp., 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.
