Shell biomechanics suggests an aquatic palaeoecology at the dawn of turtle evolution
The turtle shell is a remarkable structure that has intrigued not only evolutionary biologists
but also engineering and material scientists because of its multi-scale complexity and …

Cranial and mandibular anatomy of Plastomenus thomasii and a new time-tree of trionychid evolution
Trionychid (softshell) turtles have a peculiar bauplan, which includes shell reductions and
cranial elongation. Despite a rich fossil record dating back to the Early Cretaceous, the …

The latest freshwater giants: a new Peltocephalus (Pleurodira: Podocnemididae) turtle from the Late Pleistocene of the Brazilian Amazon
Overkill of large mammals is recognized as a key driver of Pleistocene megafaunal
extinctions in the Americas and Australia. While this phenomenon primarily affected mega …

The role of climate on the emergence of giant caimanines (Crocodylia, Alligatoroidea) from the Miocene western Amazonian region
Extant caimanines include the six modern species of caimans, which occur predominantly in
South and Central America and are mostly medium-sized crocodylians. Nevertheless, the …

Shell Constraints on Evolutionary Body Size–Limb Size Allometry Can Explain Morphological Conservatism in the Turtle Body Plan
Turtles are a small clade of vertebrates despite having existed since the Late Triassic.
Turtles have a conservative body plan relative to other amniotes, characterized by the …

The two-scale fractal dimension: a unifying perspective to metabolic law
The laws governing life should be as simple as possible; however, theoretical investigations
into allometric laws have become increasingly complex, with the long-standing debate over …

New insights into the early morphological evolution of sea turtles by re-investigation of Nichollsemys baieri, a three-dimensionally preserved fossil stem chelonioid …
JCL Menon, DB Brinkman, G Hermanson… - Swiss Journal of …, 2024 - Springer
The early evolution of Pan-Chelonioidea (sea turtles) is poorly understood. This is in part
due to the rarity of undeformed skulls of definitive early stem chelonioids. In this work, we …

Simple shell measurements do not consistently predict habitat in turtles: a reply to Lichtig and Lucas (2017)
Inferring palaeoecology for fossils is a key interest of palaeobiology. For groups with extant
representatives, correlations of aspects of body shape with ecology can provide important …

Cladistic estimates of evolutionary rates focused on palaeontological datasets using TNT
We describe a protocol for estimating evolutionary rates from phylogenetic trees based on
parsimony character optimization. The rate estimation is conducted through a TNT script and …
