Ingentidens

Ingentidens is an extinct genus of chroniosuchid reptiliomorph from upper Permian mudstone deposits of Dashankou locality, Xidagou Formation of China. It was first named by Jin-Ling Li and Zheng-Wu Cheng in 1999, from a mandible. The type species is Ingentidens corridoricus. The generic name means “large” + “tooth” (dens), and the specific name referring to the region of Gansu, the Hexi Corridor where the type specimen was found.

Time the record covers

At most 11 million years on record.

The one occurrence read is dated to somewhere between 274.4 Mya and 264.28 Mya, which is a dating window rather than a span.

1 occurrence of Ingentidens 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.
