Carcharomodus escheri

Carcharomodus is an extinct dubious genus of lamnid shark. Its only species is Carcharomodus escheri, The actual valid name of C. escheri is Isurus subserratus (escheri). Commonly nicknamed the serrated mako shark or Escher's mako shark. It was once interpreted as a transitional form between the broad-toothed ‘mako’ Carcharodon hastalis and the modern great white shark, but is now regarded as a distinct evolutionary lineage rather than a direct ancestor, particularly following the discovery of Carcharodon hubbelli, which clarified the great white shark’s evolutionary history.

11 occurrences of Carcharomodus escheri on record, most of them in the Miocene. 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

11 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 10 sites for Carcharomodus escheri, 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.

10 references

Each of the 11 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. Entries link to doi.org where the Paleobiology Database holds an identifier, and to its own record where it does not.
