Meemannia eos

Meemannia is a genus of extinct bony fish from the early Devonian period. It was initially classified as a lobe-finned fish; however, a restudy conducted by Lu et al. (2016) indicates that it was actually an early-diverging ray-finned fish. It was found in Yunnan, China. As preserved, it consists mainly of skull roofing bones and a partial otic region of the braincase. Its anatomy is unique in a number of features that resemble ray-finned fishes (Actinopterygii), and more generalized jawed vertebrates.

Time the record covers

At most 6.6 million years on record.

The one occurrence read is dated to somewhere between 419.62 Mya and 413.02 Mya, which is a dating window rather than a span.

1 occurrence of Meemannia eos on record, most of them in the Devonian. 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.
