An extinct genus of crocodyllian, Pristichampsus grew up to ten feet in length. Bizarrely it had hoof-like toes and was probably a land dweller. It was capable of galloping, and even standing on its rear hind legs. Its teeth were sharp and serrated, ideal for hunting primitive mammals.http://scienceblogs.com/afarensis/2008/10/19/crocodylian_snout_shape/

- Onderzoekers hebben in een museum in Thailand het fossiel van een honderd miljoen jaar oude krokodil gevonden. De krokodillensoort had langere poten dan hedendaagse krokodillen en at voornamelijk vis. Dat zou blijken uit zijn gebit.

"Ze leefden op land en konden niet erg hard rennen", aldus Komsorn Lauprasert, wetenschapper van de universiteit Mahasarakham.

.Het fossiel is zo'n vijftien centimeter lang en werd opgegraven in de provincie Nakhon Rathchasima, ook Korat genoemd. Het werd niet als nieuwe soort gezien en belandde in een museum, waar het in 2006 werd herontdekt.

De soort is Khoratosuchus jintasakulie gedoopt, naar de provincie Korat en Pratueng Jintasakul, aldus de directeur van het Noordoostelijk Onderzoeksinstituut voor Versteend Hout en Minerale Bronnen. De vondst is beschreven in een artikel van de Geological Society of London.

Het noordoosten van Thailand is de afgelopen jaren een belangrijke onderzoeksplek geworden voor paleontologen.

In de zogenaamde dinosaurus-riem, een plek waar sedimentair gesteente uit het Mesozoïcum door het aardoppervlak puilt, zijn tal van prehistorische fossielen gevonden.

De Cerrejonisuchus improcerus werd maximaal twee meter lang. Oftewel, de krokodil was een gemakkelijke prooi voor de Titanoboa. “De Cerrejonisuchus improcerus maakte deel uit van de voedselketen, als jager en als prooi”,vertelt onderzoeker Jonathan Bloch van het Florida Museum. “Tegenwoordig eten grote slangen kleine krokodillen op. Het is dus aannemelijk dat de Cerrejonisuchus improcerus vaak op het menu van de Titanoboa’s stond.”

In het Amazonegebied verorberen anaconda’s regelmatig kaaimannen. Hieruit blijkt dat slangen krokodillenvlees lusten

American Museum Novitates. 3631:1-19.

 

 

AbstractWe describe new dyrosaurid fossils from three localities in Mali, representing strata of Maastrichtian, Paleocene, and Eocene ages. The fossils significantly extend the temporal and geographic ranges of several known dyrosaurid taxa. Rhabdognathus keiniensis and Chenanisuchus lateroculi are identified for the first time from Maastrichtian sediments. Additional material is referred to Phosphatosaurus gavialoides and, tentatively, the genus Sokotosuchus. These discoveries represent the first occurrence of Chenanisuchus and possibly of Sokotosuchus from Mali. Previously unknown morphological character states are incorporated into existing data matrices, reducing the amount of missing data. Phylogenetic analyses largely corroborate prior hypotheses of dyrosaurid relationships, but indicate a need for new characters to resolve the relationships of certain genera and species. The occurrence of both basal (e.g., Chenanisuchus lateroculi) and highly nested (e.g., Rhabdognathus keiniensis) members of Dyrosauridae on both sides of the K/T boundary indicates that dyrosaurid diversification was well underway by the latest Cretaceous, and that most, if not all dyrosaurid species survived the extinction event. The geology of the Mali’s Tilemsi Valley is clarified; some rocks previously assigned to the Iullemmeden Basin actually represent extensions of other basins: the Taoudeni Basin and Gao Trench.

'Toyotamaphimeia Machikanense Machikane crocodile fossil specimen

A crocodile fossil discovered when excavating for the construction of a new School of Science building for Osaka University in 1964. Judging from the geological stratum, it is believed that the fossil dates from 430,000 to 380,000 years before. The fossil has received world recognition as a rare specimen from this period, and upon reexamination by Ryosuke Aoki has been advocated to receive a new biological classification as a new species, i.e. 'Toyotamaphimeia Machikanense.' There are points

concerning the scientific name and original state of the fossil which remain unconfirmed and we await the research of specialists on this valuable fossil. The Museum of Osaka Universityhttp://www.museum.osaka-u.ac.jp/en/specimen/12.html
