Lontra longicaudis annectens

The Northern Neotropical river otter, formerly classified as Lutra longicaudis annectens has recently been elevated to species status. This otter species is found in Central America and northwestern South America. Its distributions is disjunct from that of the other subspecies of Neotropical river otters and recent studies indicate that L. longicaudis is paraphyletic and that this subspecies should be recognized as a separate species Lontra annectens. This taxon is still regarded as a subspecies of Neotropical river otter by the IUCN.

Time the record covers

At most 12 thousand years on record.

The one occurrence read is dated to somewhere between 11.7 ka and 0 Mya, which is a dating window rather than a span.

1 occurrence of Lontra longicaudis annectens on record, most of them in the Holocene. 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

1 occurrences

Holocene100%

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.
