Mesoblattinidae
Mesoblattinidae is an extinct, problematic family of cockroaches known from the Mesozoic. It was formerly considered a wastebasket taxon for Mesozoic cockroaches, but the family has subsequently been better defined, with many taxa transferred to Caloblattinidae. It is considered to have close affinities with Blattidae and Ectobiidae, as well as possibly Blaberidae. The family first appeared by the Early Jurassic. They are considered to represent amongst the oldest groups of modern cockroaches, and like them are thought to have laid oothecae. Due to the poor ability of forewing venation to correctly classify cockroaches to extensive homoplasy, the value of this family as a taxonomic unit has been strongly questioned, with some authors considering the family a nomen dubium.

Time the record covers
At least 245 million years on record.
The record covers at least 307.4 Mya to 61.66 Mya. No occurrence read is dated outside 309.8 Mya to 56 Mya.
232 occurrences of Mesoblattinidae on record, most of them in the Early 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.

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 143 sites for Mesoblattinidae, 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.
