are lizards related to dinosaurs

Introduction

The relationship between lizards and dinosaurs is a topic of significant interest in paleontology. Understanding this relationship involves examining the evolutionary traits and common ancestors shared by these groups. This synthesis aims to provide insights into whether lizards are related to dinosaurs based on recent research findings.

Key Insights

Bipedalism in Dinosaurs and Lizards:
- Bipedalism, a trait common among dinosaurs, is suggested to have evolved for enhanced running capabilities. Modern lizards, which can assume a bipedal stance when fleeing predators, offer an analog for the early stages of dinosaur bipedalism evolution.
Evolutionary Lineage and Common Ancestors:
- The study of Parophisaurus pawneensis, a primitive anguid lizard, indicates that certain lizard groups share a distant common ancestor with other reptiles. This suggests that while lizards and dinosaurs may share some evolutionary traits, they diverged significantly over time.

Conclusion

Lizards and dinosaurs share some evolutionary traits, such as bipedalism, which may have evolved for similar functional reasons. However, the evolutionary lineage of lizards indicates a significant divergence from the line that led to dinosaurs. While there are common ancestors far back in their evolutionary history, lizards and dinosaurs are distinct groups with different evolutionary paths.

Parophisaurus pawneensis (Gilmore, 1928) New Genus of Anguid Lizard from the Middle Oligocene of North America

Parophisaurus pawneensis is a primitive, fully limbed fossil anguid lizard from the middle Oligocene of North America, related to Ophisaurus and possibly sharing a common limbed ancestor with Old World and New World "anguines" in

The first lizard fossil (Reptilia: Squamata) from the Mesozoic of South Korea

Asprosaurus bibongriensis is the first large-sized Mesozoic lizard fossil from South Korea, with close similarities to modern monstersaurs and dietary preferences similar to those of the living genus.

An electrophoretic study of the hemoglobins of the sand lizards, Callisaurus, Cophosaurus, Holbrookia and Uma.

The sand lizards Callisaurus, Cophosaurus, Holbrookia, and Uma share the same hemoglobin components, suggesting they are more closely related than their current taxonomic status suggests.

A large predatory lizard (Platynota, Squamata) from the Late Cretaceous of South China

Chianghsia nankangensis is a new species of large terrestrial predatory lizard from the Late Cretaceous Nanxiong Formation in southern China, indicating its association with the Platynota group and the extinct mosasaurs.

A new polyglyphanodontine lizard (Squamata: Borioteiioidea) from the Late Cretaceous Iharkut locality (Santonian, Hungary)

Distortodon rhomboideus is a new polyglyphanodontine lizard from the Late Cretaceous Iharkut locality, suggesting connections between the western Tethyan archipelago and North America in the Late Cretaceous.

A new lizard from the Early Cretaceous of Catalonia (Spain), and the Mesozoic lizards of the Iberian Peninsula

Pedrerasaurus latifrontalis is a new lizard species from the Early Cretaceous of Catalonia, Spain, with bicuspid teeth and potential for phylogenetic relationship to Meyasaurus.

Paramacellodid lizard skulls from the Jurassic Morrison Formation at Dinosaur National Monument, Utah

The new skull material of Paramacellodus lizard from the Morrison Formation reveals its anatomy and placement as a sister taxon to Scincoidea (Cordyliformes + Scincidae) rather than Cordyliformes alone.

At the feet of the dinosaurs: the early history and radiation of lizards

Squamates evolved by the middle Triassic and diversified into major lineages before the end of this period, but the early squamate fossil record is extremely patchy, constraining palaeobiogeographic discussions and limiting our understanding of squamate skull kinesis.

Untangling the dinosaur family tree

The Ornithoscelida hypothesis is not the final word on the dinosaur family tree, as there is still great uncertainty about its basic structure and origin.
