Aberlemnia sp.

Aberlemnia is a genus of extinct vascular plants of the Early Devonian, which consisted of leafless stems with terminal spore-forming organs (sporangia). Fossils found in Scotland were initially described as Cooksonia caledonica. A later review, which included new and more complete fossils from Brazil, showed that the specimens did not fit the circumscription of the genus Cooksonia; accordingly a new genus Aberlemnia was proposed.

Time the record covers

At most 3.1 million years on record.

The one occurrence read is dated to somewhere between 422.7 Mya and 419.62 Mya, which is a dating window rather than a span.

1 occurrence of Aberlemnia sp. on record, most of them in the Silurian. 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.
