Tarletonbeania crenularis

Tarletonbeania crenularis is a species of lanternfish. The first member of this species was retrieved by Dr. Tarleton H. Bean off of Vancouver Island in 1880, which is where the genus name originates from. The species name comes from the Latin word for a small notch (crenula), and this refers to the slight notch seen at the edges of the scales.

8 occurrences of Tarletonbeania crenularis 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

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.

The Paleobiology Database records 8 sites for Tarletonbeania crenularis, 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.
