Time the record covers

At most 11 million years on record.

Every occurrence read is dated to somewhere between 251.902 Mya and 241.464 Mya, and nothing in the dating separates them, so that window is what the record shows rather than a span.

152 occurrences of Juvenites on record, most of them in the Early Triassic. 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

152 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 Juvenites has been recovered from, largest first. Drawn where the rock is now, not where it formed. One further formation holds fewer occurrences and is not listed. 51 occurrences have no formation on record, which is common for older literature.

434 taxa

The Paleobiology Database records 117 sites for Juvenites, 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

44 references

Each of the 152 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. 32 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.

No 3D scan of Juvenites was found in Sketchfab.

Smithsonian Open Access and MorphoSource were not reached for this taxon, so this list is what the others held rather than everything there is.

This is what the site found, which is not the same as what exists.
