Archeria

Archeria is a genus of embolomere which lived in the Early Permian of Texas and Oklahoma. It was a medium-sized aquatic predator, with an elongated body and tail. The limbs were proportionally small but well-developed, connected to robust limb girdles. The skull was moderately long and low, up to 30 cm in length. Unlike most embolomeres, Archeria had many small chisel-shaped teeth instead of large fangs.

23 occurrences of Archeria 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

23 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.

13 references

Each of the 23 occurrences read was entered from one of these publications, ordered by how many each accounts for. This is not a search for papers mentioning the name. 1 further reference is not listed. Entries link to doi.org where the Paleobiology Database holds an identifier, and to its own record where it does not.
