Notiosorex crawfordi

Crawford's gray shrew, also known as the desert shrew, is a small shrew found in the southwestern United States and northern Mexico. It is a member of the family Soricidae of the order Eulipotyphla. It was the only known member of the genus Notiosorex until two species, N. villai distributed in the Mexican state of Tamaulipas, and N. evotis distributed along the northwest coast of Mexico, were named. A fourth distinct species, N. cockrumi, was discovered in the U.S. state of Arizona and named in 2004.

13 occurrences of Notiosorex crawfordi on record, most of them in the Pleistocene. 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

13 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 13 sites for Notiosorex crawfordi, 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.

11 references

Each of the 13 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.
