Ptychodontidae

Ptychodus is a genus of extinct durophagous (shell-crushing) lamniform sharks from the Cretaceous period, spanning from the Cenomanian to the Campanian. Fossils of Ptychodus teeth are found in many Late Cretaceous marine sediments worldwide.

397 occurrences of Ptychodontidae on record, most of them in the Late Cretaceous. 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

397 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 253 sites for Ptychodontidae, 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.

125 references

Each of the 397 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. 113 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.
