Lagenorhynchus

Lagenorhynchus is a genus of oceanic dolphins in the infraorder Cetacea, that formerly contained six extant species. However, there was consistent molecular evidence that the genus is polyphyletic and several of the species moved to other genera, leaving only the white-beaked dolphin in this genus among extant species. In addition, the extinct species Lagenorhynchus harmatuki is also classified in this genus.

20 occurrences of Lagenorhynchus on record. 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

20 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.

526 taxa

The Paleobiology Database records 18 sites for Lagenorhynchus, 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

10 references

Each of the 20 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.
