Batrachosauroides

Batrachosauroides is an extinct genus of prehistoric salamander known from several sites across the United States. The two identified species are Batrachosauroides dissimulans and Batrachosauroides gotoi. A proposed, unidentified third species has been proposed by paleontologist James Gardner based on the discovery of a dental fossil in the Bushy Tailed Blowout area of the Lance Formation fossil grounds, but has not been definitively identified as a new species or as part of either of the two identified species.

No picture of Batrachosauroides was found. Wikipedia, Wikidata and iDigBio were searched and had none. Smithsonian Open Access did not answer, so this is what the others held rather than everything there is. GBIF was asked, and what came back is not recorded: nothing, or a picture this site could not tie to Batrachosauroides, or no answer at all. This entry cannot say which.

8 occurrences of Batrachosauroides 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

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.

320 taxa

The Paleobiology Database records 8 sites for Batrachosauroides, 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

8 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.
