Tibia (Hippochrenes) fissura

Tibia fissura (Coquebert & Brongniart, 1793), a relative of Tibia (Hippochrenes) fissura — not Tibia (Hippochrenes) fissura itself

Not Tibia (Hippochrenes) fissura. This is Tibia fissura (Coquebert & Brongniart, 1793), a relative — both are Hippochrenidae.

Time the record covers

At most 11 million years on record.

Every occurrence read is dated to somewhere between 48.07 Mya and 37.71 Mya, and nothing in the dating separates them, so that window is what the record shows rather than a span.

6 occurrences of Tibia (Hippochrenes) fissura on record, most of them in the Eocene. 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

6 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.

346 taxa

The Paleobiology Database records 6 sites for Tibia (Hippochrenes) fissura, 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.

4 references

Each of the 6 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 the Paleobiology Database's own record for the work.

No 3D scan of Tibia (Hippochrenes) fissura 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.
