What is Geosaurus? Redescription of Geosaurus giganteus (Thalattosuchia: Metriorhynchidae) from the Upper Jurassic of Bayern, Germany
MARK THOMAS YOUNG and MARCO BRANDALISE DE ANDRADE
The holotype and referred specimens of Geosaurus giganteus, a metriorhynchid crocodile from the Tithonian (Upper Jurassic) of Germany, is redescribed, along with a historical overview of the genus and species. This taxon is unique among metriorhynchids as its serrated, strongly lateromedially compressed dentition is arranged as opposing blades, suggesting it was adapted to efficiently slice through fleshy prey. A new phylogenetic analysis of Crocodylomorpha is presented, which finds G. giganteus to be nested within what is currently considered Dakosaurus, whereas the other species currently assigned to Geosaurus form a clade with Enaliosuchus and the holotype of Cricosaurus.
The phyletic relationship of G. giganteus with other metriorhynchids indicates that the current definition of the genus Geosaurus is polyphyletic, and that the inclusion of subsequent longirostrine species to this genus is in error. The re-analysis presented herein demonstrates Geosaurus to be composed of three species sensu stricto. The appropriate taxonomic amendments to the Metriorhynchidae are also provided.

20 endangered Siamese crocodiles hatch in Laos
By JERRY HARMER, Associated Press – 1 day ago
VIENTIANE, Laos (AP) — One of the world’s rarest crocodile species has moved a little bit further from extinction with the hatching of 20 wild eggs plucked from a nest found in southern Laos.
Experts believe there could be as few as 300 Siamese crocodiles remaining in the world’s swamps, forests and rivers, so the discovery of the nest — the first found in the mountainous, jungle-clad country since 2008 — is a significant step in the rehabilitation of a species that was declared extinct in the wild in 1992.
Since then, tiny populations have been discovered in remote corners of its range, which used to include most of Southeast Asia. Still, the crocs remain critically endangered, according to the International Union for Conservation of Nature’s Red List, the acknowledged authority on the status of global biodiversity.
Under the soft red light of an incubator, the 20 baby crocodiles tapped and cracked their way into the world last week. Their nest was found in the southern province of Savannakhet in June by a team of villagers trained by the New York-based Wildlife Conservation Society, which is working to save the species in landlocked Laos.
“The feeling was one of elation,” Chris Hallam, who coordinates the organization’s crocodile project in Laos, told The Associated Press about the hatching.
“When you look at the global population and the population in Laos it represents quite a significant number of individual crocodiles,” he said.
The crocs were hatched at the Lao Zoo, just outside Vientiane, where they were moved to protect them from predators such as snakes and monitor lizards.
Hallam said the crocodiles will be raised in captivity for 18 months before being released back into the wild.
And it seems they won’t be alone. Villagers recently found another nest in Savannakhet with 20 eggs inside. Because those crocs are so near to hatching, conservationists decided to leave them where they are with village teams keeping an eye on them.
The Siamese crocodile grows up to 10 feet (3 meters) in length but is generally docile. Their passive nature made them all the easier to hunt. In recent decades thousands were captured and sold to crocodile farms that sprung up across Southeast Asia, feeding a vogue for its renowned soft skin and a taste for its meat.
Several thousand of the crocodiles remain in farms and in zoos, though many have been crossbred with bigger species, reducing still further the numbers of pure Siamese crocodiles.
