Turtle body size evolution is determined by lineage-specific specializations rather than global trends. [PDF]

Ecol Evol, 2023
In this work, we characterize deep‐time patterns of body evolution in turtles (Testudinata), using the most comprehensive dataset to date and employing different comparative methods. Our results suggest that through‐time patterns of turtle body evolution were determined by lineage‐specific specializations, such as habitat choice.

Pharmacological restraint of captivity giant Amazonian turtle Podocnemis expansa (Testudines, Podocnemididae) with xylazine and propofol Contenção farmacológica de tartaruga da Amazônia Podocnemis expansa (Testudines, Podocnemididae) de cativeiro com xilazina e propofol

Acta Cirúrgica Brasileira, 2008
PURPOSE: Identify a technique to induce brief sedation and hypnosis in Podocnemis expansa. METHODS: Twenty commercially bred P. expansa, weighing on average 1.2 ± 0.24 kg, were subjected to two protocols: G1 was given 1.5 mg/kg IM of xylazine and ...

Neuroanatomical study of the podocnemidid turtle Neochelys arenarum (Pleurodira), from the early Eocene of France. [PDF]

Anat Rec (Hoboken)
Abstract Neochelys is an exclusively European Eocene podocnemidid genus belonging to a linage that reached this continent at the early Eocene. The so far available anatomical information about it is relatively abundant, especially considering that of its shell, at least partially preserved for the eight valid species currently considered.

Shell characterization of the youngest valid species of the European Eocene genus Neochelys (Pleurodira, Podocnemididae): The Spanish Bartonian Neochelys salmanticensis. [PDF]

Anat Rec (Hoboken)
Abstract The freshwater pleurodiran turtle Neochelys is the best‐represented member of Podocnemididae in the European record, being known by eight Eocene species. The youngest of them is the Bartonian (middle Eocene) Neochelys salmanticensis, from the Duero Basin (Salamanca Province, Central Spain).

Phylogeny, biogeography and diversification patterns of side-necked turtles (Testudines: Pleurodira). [PDF]

R Soc Open Sci, 2018
Pleurodires or side-necked turtles are today restricted to freshwater environments of South America, Africa– Madagascar and Australia, but in the past they were distributed much more broadly, being found also on Eurasia, India and North America, and ...

Prehatch Calls and Coordinated Birth in Turtles. [PDF]

Ecol Evol
The study investigates the phylogenetic distribution of within‐egg vocal behaviour among turtles and its role in synchronous hatching. Clutches from six turtle species with diverse ecological and reproductive niches were recorded, aiming to understand if asynchronous species vocalise from within the egg, the influence of clutch size on synchronous ...

Postcranial anomalies of Eocene freshwater pleurodiran and cryptodiran turtles from the Spanish Duero Basin. [PDF]

Anat Rec (Hoboken)
Abstract Testudines are one of the best‐represented taxonomic groups among the Paleogene taxa of the Duero Basin (Castile and Leon Autonomous Community, central Spain). Among them, Neochelys (Podocnemidide) and Allaeochelys (Carettochelyidae) are most abundant, allowing the population to be assessed for osteological anomalies.
