Hemiauchenia

Searched as Hemiauchenia cf. vitakerianus. The Paleobiology Database treats Hemiauchenia as the accepted name.

Hemiauchenia is an extinct genus of lamine camelids that evolved in North America in the Miocene epoch about 10 million years ago. This genus diversified and entered South America in the Late Pliocene about three to two million years ago, as part of the Great American Biotic Interchange. The genus became extinct at the end of the Pleistocene. The monophyly of the genus has been considered questionable, with phylogenetic analyses finding the genus to paraphyletic or polyphyletic, with some species suggested to be more closely related to living lamines than to other Hemiauchenia species.

Time the record covers

At most 2.6 million years on record.

The one occurrence read is dated to somewhere between 2.58 Mya and 11.7 ka, which is a dating window rather than a span.

1 occurrence of Hemiauchenia on record, most of them in the Pleistocene. 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

1 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.

1,860 taxa

The Paleobiology Database records 259 sites for Hemiauchenia, 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.

1 reference

Each of the 1 occurrence 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. Each entry links to the Paleobiology Database's own record for the work.
