Ophisaurus ventralis

The eastern glass lizard is a species of legless lizard in the family Anguidae and the longest and heaviest species of glass lizards in the genus Ophisaurus, endemic to the Southeastern United States. The streamlined, legless species is often confused with snakes. Glass lizards differ from snakes as they possess a moveable eyelid and an external ear opening as well as a lateral groove that separates the different types of scales on the animal, while all three of these features are absent in snakes. Snakes also have flexible jaws while lizards do not. Ventralis comes from the Latin "venter" meaning belly; this is in reference to the snake-like movement.

7 occurrences of Ophisaurus ventralis on record, most of them in the Pleistocene. The Paleobiology Database records this as a living group. 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

7 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.

248 taxa

The Paleobiology Database records 7 sites for Ophisaurus ventralis, and this reads all of them. The number is how many of those sites it was catalogued from too. The 24 sharing the most are listed.

This is not a list of everything alive at the time. It is only what has come out of the same ground as this animal and been written down.

Entered from

6 references

Each of the 7 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. Entries link to doi.org where the Paleobiology Database holds an identifier, and to its own record where it does not. Relayed as the Paleobiology Database holds them, not checked against what they resolve to.
