Eostriatolamia

Eostriatolamia is an extinct genus of sharks in the family Odontaspididae. It was described by Gluckman in 1980. A new species, E. paucicorrugata, was described from the Cenomanian of Canada by Charlie J. Underwood and Stephen L. Cumbaa in 2010.

No picture of Eostriatolamia was found. Wikipedia, Wikidata, iDigBio and Smithsonian Open Access were searched and had none. GBIF was asked, and what came back is not recorded: nothing, or a picture this site could not tie to Eostriatolamia, or no answer at all. This entry cannot say which.

Time the record covers

At least 72 million years on record.

The record covers at least 145.06 Mya to 72.2 Mya. No occurrence read is dated outside 149.2 Mya to 66 Mya.

88 occurrences of Eostriatolamia 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

88 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.

766 taxa

The Paleobiology Database records 80 sites for Eostriatolamia, 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.

Entered from

36 references

Each of the 88 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. 24 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.
