***Infernovenator*** is a genus of [Carboniferous](/source/Carboniferous) [lysorophian](/source/Lysorophia) [recumbirostran](/source/Recumbirostra) from the [Mazon Creek](/source/Mazon_Creek_fossil_beds) [lagerstätte](/source/Lagerst%C3%A4tte) in Illinois, U.S. It was described in 2019.[1]

## History of study

The holotype, now reposited at the [Field Museum](/source/Field_Museum_of_Natural_History), was previously described by Godfrey (1997) as an aïstopod, *Phlegethontia longissama*.[2] Redescription of the specimen led to its identification as a new lysorophian taxon. *Infernovenator* is represented only by the holotype, a nearly complete skeleton. The genus name is given for the Latin *infernum* ("hell") to refer to the fossorial habitats of the taxon and *venator* ("hunter"). The species name honors paleontologist Margaret Clair Steen Brough.[1]

## Anatomy

*Infernovenator* is diagnosed by a unique combination of features:[1] (1) 61 presacral vertebrae; (2) a triangular postfrontal that contacts the tabular; (3) a circumorbital series formed by the prefrontal, the postfrontal, the lacrimal, and the maxilla; and (4) an ossified septomaxilla. Features shared with the lysorophian *Brachydectes* and not with other recumbirostrans include: (1) postorbital absent and cheek emargination present; (2) bar-like tabular-squamosal complex; and (3) short and robust dentary.

## Taxonomy

Below is the strict consensus topology recovered from the maximum parsimony analysis of Mann et al. (2019):[citation needed]
