Actiosaurus gaudryi

Actiosaurus is an extinct genus of reptile first described by Henri Sauvage in 1883 from Antully bonebed, Autun. The type species is A. gaudryi. Little is known of it, and it is considered a nomen dubium. Actiosaurus was originally described as a dinosaur in 1883 and was reinterpreted as an ichthyosaur in 1908. Actiosaurus may instead represent the remains of a choristodere. Fischer et al. (2014) considered A. gaudryi to be a species inquirenda, and noted the similarity of its bones to the limb bones of choristoderes.

Time the record covers

At most 4.3 million years on record.

The one occurrence read is dated to somewhere between 205.7 Mya and 201.4 Mya, which is a dating window rather than a span.

1 occurrence of Actiosaurus gaudryi on record, most of them in the Late Triassic. 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.
