Nasolamia velox

The whitenose shark is a species of shark of the family Carcharhinidae. The only member of the genus Nasolamia, it is found in the tropical waters of the eastern Pacific Ocean between latitudes 31° N and 18° S, between depths of 15 to 200 m. It can grow up to a length of 1.5 m. The whitenose shark is viviparous, with five young in a litter, and a birth size around 53 cm.

Time the record covers

At most 4 million years on record.

Every occurrence read is dated to somewhere between 5.333 Mya and 1.4 Mya, and nothing in the dating separates them, so that window is what the record shows rather than a span.

2 occurrences of Nasolamia velox on record, most of them in the Pliocene. The Paleobiology Database records this as a living group, and the chart stops with its fossils rather than at the present. 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.

32 taxa

The Paleobiology Database records 2 sites for Nasolamia velox, 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.

2 references

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 the Paleobiology Database's own record for the work.
