Variation in the skulls of Elgaria and Gerrhonotus (Anguidae, Gerrhonotinae) and implications for phylogenetics and fossil identification
TLDR
The purported diagnostic utility of many previously described morphological features is impacted because of substantial morphological variation between and within species, and the utility of examining disarticulated cranial elements of the squamate skull to identify diagnostic morphology is demonstrated.
Deconstructing the Gestalt: New concepts and tests of homology, as exemplified by a re‐conceptualization of “microstomy” in squamates
TLDR
It is proposed that non-snake lizards, early-diverging alethinophidians, anomalepidids, leptotyphlopids, and typhlopoids each exhibit a unique and nonhomologous jaw morphotype, which reflects a hypothesis of the independent evolution of fossoriality, miniaturization, and "microstomy" in each scolecophidian lineage.
Heloderma (Helodermatidae; Squamata) from the Apache Local Fauna, Pleistocene, Southwestern Oklahoma
Abstract. Paleontological occurrences of helodermatid lizards (Helodermatidae) are relatively uncommon and scattered in the North American fossil record. A recently discovered concentration of
First evidence of convergent lifestyle signal in reptile skull roof microanatomy
TLDR
It is found that fossoriality evolved independently in 54 lepidosaur lineages and a highly compact skull roof, small skull diameter, elongate cranium, and low length ratio of frontal and parietal were repeatedly acquired in concert with a fossorial lifestyle.
Evolution, diversity and interactions with past human populations of recently extinct Pholidoscelis lizards (Squamata: Teiidae) from the Guadeloupe Islands (French West-Indies)
TLDR
It is demonstrated how subfossil bone remains from Pleistocene and Holocene deposits can help to reconstruct the history of recently extinct taxa through the example of Pholidoscelis lizards from the Guadeloupe Islands in the French West Indies.
Fossil amphibians and reptiles from the Neogene locality of Maramena (Greece), the most diverse European herpetofauna at the Miocene/Pliocene transition boundary
TLDR
The large number of distinct amphibian and reptile taxa in Maramena makes this Greek locality by far the most diverse and speciose among all European localities across the latest Miocene and earliest Pliocene.
The Oligocene and Miocene fossil lizards (Reptilia, Squamata) of Central Mongolia
ABSTRACT Lizard material from the early Oligocene and early and late Miocene of the Valley of Lakes, Central Mongolia is described. Besides the Oligocene fossorial squamate published elsewere, the
The first known fossil Uma: ecological evolution and the origins of North American fringe-toed lizards
TLDR
It is demonstrated that an apomorphy-based diagnosis can be used to identify fossils of isolated skeletal elements for at least one clade of phrynosomatid lizard, and suggested exercising caution when using environmental tolerances of extant taxa to hypothesize paleoecological reconstructions.
The internal cranial anatomy of Champsosaurus lindoei and its functional implications
TLDR
The presence of the putative neomorphic bone is confirmed, which may be homologous with the pre-existing stapes, or developed through incomplete fusion of dermatocranial ossification centres, and geometric morphometric analyses of the semicircular canals suggest that Champsosaurus were well adapted for an aquatic lifestyle.
Identifying Gecko Species from Lesser Antillean Paleontological Assemblages: Intraspecific Osteological Variation within and Interspecific Osteological Differences between Thecadactylus rapicauda (Houttuyn, 1782) (Phyllodactylidae) and Hemidactylus mabouia (Moreau de Jonnès, 1818) (Gekkonidae)
TLDR
This study presents nine osteological characters, allowing for a fully reliable distinction of these two gecko species, both currently occurring in the Lesser Antilles and in the subfossil assemblages of the region.
