Time the record covers

At most 16 million years on record.

Every occurrence read is dated to somewhere between 298.9 Mya and 283.3 Mya, and nothing in the dating separates them, so that window is what the record shows rather than a span.

2 occurrences of Dimetrodon milleri 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

2 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.

Found in the same rock

The Paleobiology Database records no fossil sites for Dimetrodon milleri, so there is nothing to compare it with.

2 references

Each of the 2 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. Each entry links to the Paleobiology Database's own record for the work.
