Huehuecuetzpalli mixtecus gen. et sp. nov: a basal squamate (Reptilia) from the Early Cretaceous of Tepexi de Rodriguez, central Mexico
TLDR
Although its appearance is late in the fossil record of lizards, Huehuecuetzpalli is the first report of a basal squamate and provides important information on early transformation of characters in lizard evolution.
AN UNUSUAL AQUATIC SPHENODONTIAN (REPTILIA: DIAPSIDA) FROM THE TLAYUA FORMATION (ALBIAN), CENTRAL MEXICO
TLDR
Cladistic analysis support sister-group relationship with Toxolophosaurus and/or Eilenodon on the basis of shared propalinal jaw action and deep jaws and the presence of two unique sphenodontians in the Tlayua Quarry suggests that this area was a refuge for archaic forms at the time.
Diversification in the northern neotropics: mitochondrial and nuclear DNA phylogeography of the iguana Ctenosaura pectinata and related species
TLDR
The influence of both Pliocene and Pleistocene events in shaping the geographical distribution of genetic variation within neotropical lowland organisms is highlighted and areas of high genetic diversity in southern Mexico were detected, have implications for the conservation of this threatened species.
Circadian rhythms in Mexican blind cavefish Astyanax mexicanus in the lab and in the field.
TLDR
It is proposed that altered expression of light-inducible genes provides a selective advantage to cavefish at the expense of a damped circadian oscillator.
A “beaded” sphenodontian (Diapsida: Lepidosauria) from the Early Cretaceous of central Mexico

  • 16 April 1997
TLDR
The conspicuous dermal skeleton is similar to that of helodermatids, suggesting that it could have served to protect against predation in open environments, and argues against the idea of low morphological diversity within sphenodontians.
A Middle Jurassic Sphenodon-like sphenodontian (Diapsida: Lepidosauria) from Huizachal Canyon, Tamaulipas, Mexico
ABSTRACT A new Middle Jurassic North American sphenodontian, Cynosphenodon huizachalensis, gen. et sp. nov. is described on the basis of several dentaries and maxillae. It is characterized by its
POSSIBLE EVIDENCE OF A VENOM APPARATUS IN A MIDDLE JURASSIC SPHENODONTIAN FROM THE HUIZACHAL RED BEDS OF TAMAULIPAS, MÉXICO
Abstract A new sphenodontid is described from the Middle Jurassic red beds in Huizachal Canyon, Tamaulipas, northern Mexico. The new taxon is characterized by the presence of two fang-like acrodont
A population matrix model and population viability analysis to predict the fate of endangered species in highly managed water systems
TLDR
It is found that the best strategy to restore the axolotl population is to increase the survival rate of eggs and larvae by restoring the habitat, eradicating introduced fish and improving water quality, rather than implementing a reintroduction programme.
Geographical structure and cryptic lineages within common green iguanas, Iguana iguana
TLDR
Investigation of genetic structure in Neotropical populations of common green iguanas (Iguana iguana) and to compare that structure with past geological events and present barriers found high levels of divergence between lineages within Iguana.
