Limb anatomy of the Triassic turtles: appendicular osteology of Proterochersis (Testudinata, Proterochersidae)
The turtle locomotor system is heavily modified owing to the severe impact of development
of the shell on the body plan of these reptiles. Although limb and girdle osteology of the …

First evidence of Proganochelys quenstedtii (Testudinata) from the Plateosaurus bonebeds (Norian, Late Triassic) of Frick, Canton Aargau, Switzerland
Proganochelys quenstedtii represents the best-known stem turtle from the Late Triassic, with
gross anatomical and internal descriptions of the shell, postcranial bones and skull based …

Appearances can be deceptive: bizarre shell microanatomy and histology in a new Triassic turtle (Testudinata) from Argentina at the dawn of turtles
The origin and homology of the turtle shell is one of the most captivating topics in amniote
evolution. In this contribution, we present a new species of turtle from the Late Triassic of …

Bromalites from a turtle-dominated fossil assemblage from the Triassic of Poland
Bromalites (coprolites and possibly some cololites) from a turtle-dominated fossil
assemblage from the Upper Triassic of Poland were studied. Bromalites collected at the …

An Upper Triassic terrestrial vertebrate assemblage from the forgotten Kocury locality (Poland) with a new aetosaur taxon
Since 1990, several localities within the Keuper (upper Middle to Upper Triassic) strata in
southern Poland have yielded remains of numerous terrestrial vertebrate species. Here we …

Natural external plastron mold of the Triassic turtle Proterochersis: An unusual mode of preservation
Impressions of vertebrate bodies or their parts, such as trace fossils and natural molds of
bones, are a valuable source of information about ancient faunas which may supplement the …

Supernumerary scutes verify a segment‐dependent model of the horny shell development in turtles
Turtle horny shell has a scute pattern, which is conservative through evolution and across
species. The discovery of epidermal placodes as the scute primordia and their strict …

Triassic turtles from Pangea: the legacy from South America
The Triassic is a key period in turtle evolution for three main reasons: First, the oldest fully
shelled body-fossil records of the clade Testudinata come from Late Triassic (Norian) rocks …
