Mytella guyanensis

Mytella guyanensis is a species of tropical saltwater mussel, marine bivalve molluscs in the family Mytilidae. This species has been referred to colloquially as the “Trinidad Swamp Mussel” —although not formally confirmed as the common name. It was first described in detail by the French naturalist Jean Baptiste Lamarck in 1819.

Time the record covers

At most 129 thousand years on record.

The one occurrence read is dated to somewhere between 129 ka and 0 Mya, which is a dating window rather than a span.

1 occurrence of Mytella guyanensis 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

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.

The Paleobiology Database records 1 site for Mytella guyanensis, 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.
