Ceratogaulus

Ceratogaulus is an extinct genus of rodents, a member of the extinct fossorial (burrowing) rodent family Mylagaulidae. Ceratogaulus is one of two rodent genera with horns and is the smallest known horned mammal. Ceratogaulus lived in North America from the late Miocene to the early Pliocene epochs, 16.3 to 5.3 million years ago. Ceratogaulus have sometimes been nicknamed "horned gophers", though they are only distantly related to true gophers.

22 occurrences of Ceratogaulus 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

22 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 22 sites for Ceratogaulus, 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.

9 references

Each of the 22 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. Relayed as the Paleobiology Database holds them, not checked against what they resolve to.
