Neazoniidae

Neazoniidae is an extinct family of planthoppers known from the Cretaceous period. It was initially named by Szwedo in 2007 based on nymphal specimens. Recently the family Mimarachnidae has been synonymized with Neazoniidae based on their unique mouthpart morphology. The family is characterized by an elongated distal segment of the labium bearing dense transverse wrinkles which has allowed it to flex, in a manner unlike all other living and extinct members of the suborder Auchenorrhyncha. This adaptation is thought to have allowed these insects to access the sap of thick barked trees.

56 occurrences of Neazoniidae on record, most of them in the Late Cretaceous. 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

56 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.

The Paleobiology Database records 31 sites for Neazoniidae, 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

26 references

Each of the 56 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. 14 further references are not listed. 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.
