Broiliellus
extinct genus
Broiliellus is an extinct genus of dissorophoid temnospondyl within the family Dissorophidae. Broiliellus is most closely related to the genus Dissorophus, and both have been placed in the subfamily Dissorophinae. Broiliellus is known from five species from the Early Permian: the type species is Broiliellus texensis, and the other species are Broiliellus brevis, Broiliellus olsoni, Broiliellus arroyoensis, and Broiliellus reiszi. An additional species, Broiliellus novomexicanus, which was originally named Aspidosaurus novomexicanus, is now thought to fall outside the genus as a member of the subfamily Eucacopinae.
History of study
Broiliellus was first named by American paleontologist S.W. Williston in 1914 based on two nearly complete skulls in articulation with postcranial material from the early Permian of Texas; this species was given the name Broiliellus texensis, the genus name being for the German paleontologist Ferdinand Broili, and the species name being for the geographic provenance. The holotype is currently reposited in the Field Museum. A second species, Broiliellus brevis, from the Archer City bonebed in Texas was named in 1964 by Canadian paleontologist Robert Carroll; the holotype of this species is currently reposited in the Museum of Comparative Zoology. Two more species were named in 1967 by American paleontologist Robert DeMar, Broiliellus olsoni and Broiliellus arroyoensis, both from Texas. The most recent species to be described was Broiliellus reiszi in 2013 by Canadian paleontologist Robert Holmes and colleagues.
Phylogeny
The phylogenetic analysis of Schoch (2012) found that Broiliellus was most closely related to Dissorophus.
Begin with the source’s own compact description: “Broiliellus” is extinct genus. The dossier treats that line as a proposition to test through Broiliellus, extinct and genus, not as a finished interpretation.
Why this record matters
The phrase “extinct genus” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated May 18, 2026. The linked authority identifier is Q1965407. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1914, 1964, 1967 and 2013.
A general summary may omit uncertainty, sample limits or methodological disagreement that is explicit in the technical record. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
