New Records of Squamates from the Upper Miocene of South America
(Society for the Study of Amphibians and Reptiles, 2013-12)
The Cerro Azul Formation of Argentina has yielded one of the highest diversities of squamate reptiles for the upper Miocene of South America including tupinambine teiids (Tupinambis sp.), ‘‘colubrids,’’ and viperids. Here, ...
An Overview of the South American Fossil Squamates
(Veterinary and Human Toxicology, 2014-03)
The evolution of squamates in South America is the result of the complex geological and paleoclimatic history of this part of the world. The incomplete and episodic fossil record allows us to know only a small part of this ...
Species composition, abundance and diet of a squamate assemblage from the Carnaval stream headwaters (Buenos Aires, Argentina)
(Springer, 2019-12)
The present work summarizes 10 years of field observations of an exurban squamate assemblage occupying a 1200 ha patch in the suburbs of La Plata City (Los Porteños, Buenos Aires, Argentina). Crossed by two streams (Martin ...
The southernmost fossil record of Squamates
(Brill Academic Publishers, 2017-01)
Squamates form a substantial part of the present-day South American herpetofauna, and their fossils constitute an indispensable evidence for understanding the origin and evolution of the main taxa. Squamates are relatively ...
Occurrence and distribution of sesamoid bones in squamates: A comparative approach
(Wiley Blackwell Publishing, Inc, 2010-07)
Sesamoids are defined as skeletal elements that develop within a continuous band of regular dense connective tissue (tendon or ligament) adjacent to an articulation or joint. In this work, we discuss developmental data on ...
Lizards and snakes Warmth-loving sunbathers
(Senckenberg, 2018)
This chapter includes the most recent advances about the study of lizards and snakes recovered in the Messel Pit (Middle Eocene), Germany.
How common are cranial sesamoids among squamates?
(Wiley-liss, Div John Wiley & Sons Inc, 2017-10)
Sesamoids are elements that originate as intratendinous structures due to genetic and epigenetic factors. These elements have been reported frequently in vertebrates, although cranial sesamoids have been recorded almost ...
The role of spatial heterogeneity in diversity of squamate reptiles in the atlantic forest highlands of southeastern Brazil
(2021-01-01)
Spatial heterogeneity of vegetation is considered to be one of the most important factors that can influence species richness in a region and, therefore, an important driver for species diversity. Here, we investigate how ...
Skeletal development in the fossorial gymnophthalmids Calyptommatus sinebrachiatus and Nothobachia ablephara
(ELSEVIER GMBH, URBAN & FISCHER VERLAGJENA, 2012)
The development of the cartilaginous and bony elements that form the skull and axial and appendicular skeleton is described in detail for the post-ovipositional embryonic development of the fossorial gymnophthalmid species ...
