Chromatogenys, new lizard from Cretaceous of Hungary + Dakotaseps (new name)

Ben Creisler

Two new papers:


László Makádi & Randall L. Nydam (2014)
A new durophagous scincomorphan lizard genus from the Late Cretaceous
Iharkút locality (Hungary, Bakony Mts).
Paläontologische Zeitschrift (advance online publication)
DOI: 10.1007/s12542-014-0253-1

The Upper Cretaceous (Santonian) Iharkút terrestrial vertebrate
locality in Hungary has already yielded scincomorphan taxa such as the
polyglyphanodontines Bicuspidon and Distortodon and the chamopsiid
Pelsochamops. Besides these, more lacertilian material is available,
including a single right mandible, different from both the
abovementioned genera from Iharkút and from other previously known
taxa. This specimen is described here as Chromatogenys tiliquoides
gen. nov. sp. nov. The open Meckelian canal, the wide subdental shelf
with deep sulcus dentalis, and the pleurodont teeth support the
referral of the specimen to Scincomorpha. Within that, Chromatogenys
differs from groups known from Iharkút, such as polyglyphanodontines
and chamopsiids, and is also distinct from other contemporary
scincomorphs from Europe, North America, and Asia. It exhibits a
combination of mixed characters, some of which are shared by scincids,
cordylids, and contogeniids. Chromatogenys might be a representative
of a new family within Scincomorpha, but its familiar relationships
should be considered to be uncertain (familia incertae sedis) until
more material is found. Chromatogenys had a durophagous dentition
similar to those of extant skinks such as Tiliqua, and most probably
had a similar diet too, composed of molluscs, eggs, insects, small
vertebrates, and fruits.
