Windermeria aitkeni

Windermeria aitkeni is a Precambrian organism from the Blueflower Formation of Sekwi Brook North, in the Northwest Territories of Canada. Only one specimen has been found. Windermeria is a small segmented elongated oval fossil with eight nearly equal-sized segments arranged transverse to medial furrow in opposite arrangement. Windermeria superficially resembles a diminutive Dickinsonia and as such is the only possible dickinsoniid proarticulatan known exclusively from outside of Australia and East Europe.

Time the record covers

At most 97 million years on record.

The one occurrence read is dated to somewhere between 635 Mya and 538.8 Mya, which is a dating window rather than a span.

1 occurrence of Windermeria aitkeni on record. 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 Windermeria aitkeni, and this reads all of them. The number is how many of those sites it was catalogued from too.

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.
