Mamulichthys ignotus

Mamulichthys is an extinct genus of bony fish in the order Discordichthyiformes only known from the middle Permian of Russia. Like other members of its order, the fish differs from the majority of other bony fish due to the presence of fin spines on its pectoral and dorsal fins. The fish is one of the most complete members of the order, with the holotype specimen preserving a majority of the body, up to around the second dorsal fin. More recently, Mamulichthys has been thought to potentially be a synonym of another member of the order ,Mutovinia, due to the similarities in their odontode shape. There is currently one species in the genus: M. ignotus.

Time the record covers

At most 7.1 million years on record.

The one occurrence read is dated to somewhere between 266.9 Mya and 259.857 Mya, which is a dating window rather than a span.

1 occurrence of Mamulichthys ignotus on record, most of them in the Permian. 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.
