abstract:  The cranial osteology of the aquatic reptile Mesosaurus tenuidens is redescribed on the basis of new and previously examined materials from the Lower Permian of both southern Africa and South America. Mesosaurus is distinguished from other mesosaurs in exhibiting an absolutely larger skull and possessing relatively longer marginal teeth. The teeth gradually angle outwards as one progresses anteriorly in the tooth row and become conspicuously procumbent at the tip of the snout. The suggestion that mesosaurs used their conspicuous dental apparatus as a straining device for filter feeding is based upon erroneous reconstruction of a high number of teeth in this mesosaur. Reinterpretation of the morphology and the organization of the marginal teeth of Mesosaurus suggests that they were used to capture individually small, nektonic prey. General morphological aspects of the skull support the idea that Mesosaurus was an aquatic predator and that the skull was well adapted for feeding in an aqueous environment. The anatomical review permits critical reappraisal of several cranial characters that have appeared in recent phylogenetic analyses of early amniotes. Emendation of problematic characters and reanalysis of amniote phylogeny using a slightly modified data matrix from the literature strengthens the hypothesis that mesosaurs form a clade with millerettids, procolophonoids and pareiasaurs within Reptilia.  © 2006 The Linnean Society of London, Zoological Journal of the Linnean Society, 2006, 146, 345–368. —The preceding unsigned comment was added by A532reptof (talk • contribs) 20:30, 18 February 2007 (UTC)

thread_title:  So, what's with the IPs? 

message: "As Mesosaurus was a coastal animal, and therefore could not have crossed the Atlantic Ocean, this distribution indicated that the two continents used to be joined together."
I don't know if this is backed up with evidence, iirc salt water crocodiles are coastal animals, but they can cross large bodies of water too. I fully realise this doesn't undermine plate tectonics, but I'm not sure it's strong evidence for it either, the strongest evidence is backed up with other facts, therefore I'm nore sure this statement helps or is warranted in it's current form ( maybe it could be changed to something along the lines it suggests plate tectonics is a valid theory? )  — Preceding unsigned comment added by 86.178.91.231 (talk) 21:35, 24 February 2012 (UTC)
