Comparisons among species have been a standard tool in animal physiology to understand
how organisms function and adapt to their surrounding environment. During the last two …

A beautifully preserved skull from the Barremian Wessex Formation of the Isle of Wight,
England, represents the first known skull of a European solemydid turtle and is referred to …

The relationship between morphometrics and phylogenetic analysis has long been
controversial. Here we propose an approach that is based on map** morphometric traits …

Extant and fossil crocodilians have long been divided into taxonomic and/or ecological
groups based on broad patterns of skull shape, particularly the relative length and width of …

Cranial morphology in birds is thought to be shaped by adaptive evolution for foraging
performance. This understanding of ecomorphological evolution is supported by …

Abstract The cichlids of East Africa are renowned as one of the most spectacular examples
of adaptive radiation. They provide a unique opportunity to investigate the relationships …

Adaptive radiation is the rapid evolution of morphologically and ecologically diverse species
from a single ancestor. The two classic examples of adaptive radiation are Darwin's finches …

Covering all facets of the biology of a little-known genus, Peter V. Lindeman's lavishly
illustrated Map Turtle and Sawback Atlas is both a scientific treatise and an engaging …

Turtles have a highly modified body plan, including a rigid shell that constrains postcranial
anatomy. Skull morphology and neck mobility may therefore be key to ecological …

Turtles are one of Earth's most instantly recognizable life forms, distinguished for over 200
million years in the fossil record. Even so, key nodes in the phylogeny of turtles remain …
