Anura

A frog is any member of a diverse and largely semiaquatic group of short-bodied, tailless amphibian vertebrates composing the order Anura. Frog species with rough skin texture due to wart-like parotoid glands tend to be called toads, but the distinction between frogs and toads is informal and purely cosmetic, and does not reflect taxonomy or evolutionary history.

Time the record covers

At least 227 million years on record.

The record covers at least 227.3 Mya to 11.7 ka. No occurrence read is dated outside 237 Mya to 0 Mya.

2,636 occurrences of Anura on record, most of them in the Pleistocene. 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

2,636 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 named rock units Anura has been recovered from, largest first. Drawn where the rock is now, not where it formed. 287 further formations hold fewer occurrences each and are not listed. 1,343 occurrences have no formation on record, which is common for older literature.

3,491 taxa

The Paleobiology Database records at least 995 sites for Anura, and this reads 240 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

725 references

Each of the 2,636 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. 713 further references are not listed. 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.
