The implication of the new labor clauses in the USMCA on labor market and trade between the United States, Mexico and Canada

Stäuble, Mathieu ; Matile, Laurent (Dir.)

Mémoire de bachelor : Haute école de gestion de Genève, 2020 ; TDIBM 93.

The North American continent has implemented different free trade agreements throughout the years. From the Canadian-United States Free Trade Agreement (CUSFTA) reached in 1989, between Canada and the United States and quickly replaced by the North American Free Trade Agreement (NAFTA) in 1994 with the addition of Mexico to the agreement. After 26 years of existence and divergent opinions...

Cranial osteology of the early cretaceous turtle Pleurosternon bullockii (paracryptodira: pleurosternidae)

Evers, Serjoscha W. ; Rollot, Yann ; Joyce, Walter G.

In: PeerJ, 2020, vol. 8, p. e9454

Pleurosternon bullockii is a turtle from the Early Cretaceous of Europe known from numerous postcranial remains. Only one skull has so far been referred to the species. Pleurosternon bullockii belongs to a group of turtles called pleurosternids, which is thought to include several poorly known taxa from the Late Jurassic and Early Cretaceous of Europe and North America. Pleurosternids and...

An alternative interpretation of Peltochelys duchastelii as a paracryptodire

Joyce, Walter G. ; Rollot, Yann

In: Fossil Record, 2020, vol. 23, no. 1, p. 83–93

Peltochelys duchastelii is an enigmatic turtle from Early Cretaceous (middle Barremian–early Aptian) Sainte-Barbe Formation of Bernissart, Belgium. In more recent literature, there has been strong support for the trionychian affinities of this taxon, but this interpretation is less consistent with external data, in particular biogeography and temporal considerations. We provide a...

The last surviving Thalassochelydia — A new turtle cranium from the Early Cretaceous of the Purbeck Group (Dorset, UK)

Anquetin, Jérémy ; André, Charlotte

In: PaleorXiv, 2020, p. 7pa5c

Background. The mostly Berriasian (Early Cretaceous) Purbeck Group of southern England has produced a rich turtle fauna dominated by the freshwater paracryptodires Pleurosternon bullockii and Dorsetochelys typocardium. Each of these species is known by numerous relatively complete shells and by a single cranium. The two other turtles found in the Purbeck Group (Hylaeochelys belli, a species of...

A new species of baenid turtle from the Early Cretaceous Lakota Formation of South Dakota

Joyce, Walter G. ; Rollot, Yann ; Cifelli, Richard L.

In: Fossil Record, 2020, vol. 23, no. 1, p. 1–13

Baenidae is a clade of paracryptodiran turtles known from the late Early Cretaceous to Eocene of North America. The proposed sister-group relationship of Baenidae to Pleurosternidae, a group of turtles known from sediments dated as early as the Late Jurassic, suggests a ghost lineage that crosses the early Early Cretaceous. We here document a new species of paracryptodiran turtle, Lakotemys...

Notes on the cheek region of the Late Jurassic theropod dinosaur Allosaurus

Evers, Serjoscha W. ; Foth, Christian ; Rauhut, Oliver W.M.

In: PeerJ, 2020, vol. 8, p. e8493

Allosaurus, from the Late Jurassic of North America and Europe, is a model taxon for Jurassic basal tetanuran theropod dinosaurs. It has achieved an almost iconic status due to its early discovery in the late, 19th century, and due to the abundance of material from the Morrison Formation of the western U.S.A., making Allosaurus one of the best-known theropod taxa. Despite this, various...
