Not Brachybelus. This is Agriopis marginaria (Fabricius), a relative.

Time the record covers

At most 14 million years on record.

Every occurrence read is dated to somewhere between 184.2 Mya and 170.9 Mya, and nothing in the dating separates them, so that window is what the record shows rather than a span.

2 occurrences of Brachybelus on record, most of them in the Middle Jurassic. 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 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.

4 taxa

The Paleobiology Database records 2 sites for Brachybelus, and this reads all of them. The number is how many of those sites it was catalogued from too.

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

1 reference

Each of the 2 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. Each entry links to doi.org. Relayed as the Paleobiology Database holds them, not checked against what they resolve to.

No 3D scan is on file for Brachybelus.

This entry was cached before the site began recording what Smithsonian Open Access, MorphoSource and Sketchfab did, so a search that failed cannot be told from one that found nothing.

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