Insect mimicry of plants dates back to the Permian
Autor: Romain Garrouste, Sylvain Hugel, Lauriane Jacquelin, Pierre Rostan, J.-Sébastien Steyer, Laure Desutter-Grandcolas, André Nel
Publikováno v: Nature Communications, Vol 7, Iss 1, Pp 1-6 (2016)
Many insects mimic plants in order to avoid detection by predators. Here, Garrouste and colleagues describe a katydid fossil that extends the record of leaf mimicry to the Middle Permian, more than 100 million years earlier than previously known foss

The only true living endothermic vertebrates are birds and mammals, which produce and regulate their internal temperature quite independently from their surroundings. For mammal ancestors, anatomical clues suggest that endothermy originated during th

Autor: Valentin Buffa, Eberhard Frey, J.-Sébastien Steyer, Michel Laurin
Publikováno v: Journal of Vertebrate Paleontology. 42
The postcranial skeleton of the gliding neodiapsid reptile Coelurosauravus elivensis (Lower Sakamena Formation, ?upper Permian, southwestern Madagascar) is re-described in detail based on all previously referred specimens. The exquisite preservation

International audience; The Xenacanthiformes from Central and Eastern European deposits have been extensively studied, but the systematics of the species from the French Carboniferous–Permian Autun Basin (Saône-et-Loire) remains debated. Numerous

Updated geology and vertebrate paleontology of the Triassic Ntawere Formation of northeastern Zambia, with special emphasis on the archosauromorphs
Autor: J. Sébastien Steyer, Roger M. H. Smith, Neil J. Tabor, Brandon R. Peecook
Publikováno v: Journal of Vertebrate Paleontology. 37:8-38
The two vertebrate fossil assemblages from the ?Middle Triassic Ntawere Formation have been known since the 1960s, but little new work has been done since the description of novel taxa in the 1960s and 1970s. Three recent field seasons have increased

A new extreme longirostrine temnospondyl from the Triassic of Madagascar: phylogenetic and palaeobiogeographical implications for trematosaurids
Autor: Lovasoa Ranivoharimanana, Stéphanie Gastou, J. Sébastien Steyer, François Escuillié, Josep Fortuny
Publikováno v: Journal of Systematic Palaeontology. 16:675-688
Trematosaurids form a very large and remarkable clade of Triassic tetrapods (Temnospondyli: Stereospondyli) with a worldwide geographical distribution. Compared with specimens from Europe, Australia or North America, they remain relatively scarce in

In response to predation pressure, some insects have developed spectacular plant mimicry strategies (homomorphy), involving important changes in their morphology. The fossil record of plant mimicry provides clues to the importance of predation pressu
