Isurus

Mako sharks are predatory mackerel sharks of the genus Isurus. They are largely pelagic, and are fast, predatory fish capable of swimming at speeds of up to 50 km/h (31 mph). The two species of mako sharks are sexually dimorphic, with females being larger than males, and are large sharks. Both species are classified as "Endangered" by the IUCN.

467 occurrences of Isurus on record, most of them in the Miocene. 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

467 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.

3,530 taxa

The Paleobiology Database records 363 sites for Isurus, and this reads 240 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

222 references

Each of the 467 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. 210 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.
