A new species of the large-headed coastal marine turtle Solnhofia (Testudinata, Thalassochelydia) from the Late Jurassic of NW Switzerland

Anquetin, Jérémy ; Püntener, Christian

In: PeerJ, 2020, vol. 8, p. e9931

Background: The large-headed turtle Solnhofia parsonsi is known by a handful of specimens from the Late Jurassic of Germany and Switzerland (maybe also France). Solnhofia parsonsi is traditionally regarded as a “eurysternid” Thalassochelydia, a group of small to medium sized, mostly lagoonal or marginal turtles found almost exclusively in the Late Jurassic of Europe. More recently,...

A review of the fossil record of turtles of the clade Thalassochelydia

Anquetin, Jérémy ; Püntener, Christian ; Joyce, Walter G.

In: Bulletin of the Peabody Museum of Natural History, 2017, vol. 58, no. 2, p. 317–369

The Late Jurassic (Oxfordian to Tithonian) fossil record of Europe and South America has yielded a particularly rich assemblage of aquatic pan-cryptodiran turtles that are herein tentatively hypothesized to form a monophyletic group named Thalassochelydia. Thalassochelydians were traditionally referred to three families, Eurysternidae, Plesiochelyidae, and Thalassemydidae, but the current...

Taxonomy and phylogeny of the turtle Tropidemys langii Rütimeyer, 1873, based on new specimens from the Kimmeridgian of the Swiss Jura Mountains

Püntener, Christian ; Billon-Bruyat, Jean-Paul ; Bocat, Loïc ; Berger, Jean-Pierre ; Joyce, Walter G.

In: Journal of Vertebrate Paleontology, 2014, vol. 34, no. 2, p. 353–374

The fossil turtle Tropidemys langii is a representative of Plesiochelyidae, a traditionally recognized group of Late Jurassic turtles diagnosed by the presence of three cervical scutes and adapted to life in the sea. Tropidemys langii was previously only known from fossilized carapaces and, possibly, plastra from Europe, most notably the famous ‘Solothurn Turtle Limestone’ of Switzerland. Due...
