K–P transition in Brazil. ( 英 文 ). Barbosa J A;Kellner A W A; Viana M S S3. Proceedings ofthe Royal Society B: Biological Sciences, 2008,275(1641): 1385-1391The discovery of a new dyrosaurid crocodylomorphfrom the well-dated Palaeocene depositsof northeastern Brazil sheds new light on theevolutionary history of this extinct group of marinecrocodylomorphs that have survived theCretaceous–Palaeogene (K–P) extinction crisis.Guarinisuchus munizi, the most complete memberof this group collected in South America sofar, is closely related to the African forms, andthis fact suggests that dyrosaurids had crossedthe Atlantic Ocean before the K–P boundary anddispersed from there to North America and otherparts of South America. This discovery alsosuggests that on the coast of northeastern Brazil,dyrosaurids replaced the pre-existing Late Cretaceousfauna of diversified mosasaurs, a group ofmarine lizards, after the K–P extinction event,becoming the main predators, together withsharks, in shallow marine Palaeocene environments.More detailed stratigraphic records anddetailed dating of the deposits with dyrosauridsare necessary to correlate this particular patternfound in the ancient northeastern Brazilian coastwithin the evolution of the group, especially inAfrica.The discovery of a new dyrosaurid crocodylomorphfrom the well-dated Palaeocene depositsof northeastern Brazil sheds new light on theevolutionary history of this extinct group of marinecrocodylomorphs that have survived theCretaceous–Palaeogene (K–P) extinction crisis.Guarinisuchus munizi, the most complete memberof this group collected in South America sofar, is closely related to the African forms, andthis fact suggests that dyrosaurids had crossedthe Atlantic Ocean before the K–P boundary anddispersed from there to North America and otherparts of South America.

Lucas S G. Stratigraphy, 2004,1(1): 47-64For about a half century, most vertebrate paleontologistshave correlated the youngest Permiantetrapod assemblages inNorth America,which are from the San Angelo, Flowerpot andChickasha formations in Texas-Oklahoma, to theoldest therapsid-bearing assemblages of the RussianKazanian. This correlation was not based onshared low-level taxa (genera and species),buton the supposed therapsids in the American faunasand the presence of some “counterparts”(equivalent evolutionary grade) amongtheAmericanand Russian captorhinids and caseid pelycosaurs.Marinebiostratigraphy indicates that theyoungest tetrapod assemblages in Texas-Oklahoma are of Kungurian (late Leonardian)age, whereas the base of the Kazanian is noolder than late Roadian. Thus, a veryreal hiatusin the global tetrapod record, previously namedOlson’s gap, is evident between the youngest,pelycosaur-dominated assemblagesof NorthAmerica and the oldest, therapsid-dominatedtetrapod assemblages of Russia. This hiatus isequivalent to most of Roadian time, and is atleast two million years long. A review of theglobal record of Permian tetrapod body fossilsand footprints revealsthat this is a hiatus ofglobal extent. Olson’s gap corresponds to a significantremodelling of the Permian tetrapodfauna.2008040445意 大 利 Friuli 地 区 晚 三 叠 世 Langobardisaurusrossii 的 修 订 = A revision of Langobardisaurusrossii Bizzarini and Muscio, 1995from the Late Triassic of Friuli (Italy).

Renesto S; Dalla Vecchia F M. Rivista Italianadi Paleontologia e stratigrafia, 2007, 113(2):191-201A nearly complete but poorly preserved amniotefrom the Middle-Upper Norian of Friuli,previously attributed to a new species of the protorosaurgenus Langobardisaurus (L. rossii), isre-described. Study reveals that the specimendoes not exhibit any protorosaurian characters,instead all available evidence supports its attributionto the Lepidosauromorpha. Some skullcharacters might support sphenodontian affinities,but preservation is too jpoor to allow a firmassignment to this group.2008040446意 大 利 撒 丁 晚 更 新 世 San Giovanni di Sinis地 区 新 的 脊 椎 动 物 化 石 : 地 中 海 中 部 最 晚 的 爬行 动 物 Mauremys = New fossil vertebrate remainsfrom San Giovanni di Sinis (Late Pleistocene,Sardinia): The last Mauremys (Reptilia,Testudines) in the central Mediterranean. ( 英 文 ).Chesi F; Delfino M; Abbazzi L; Carboni S;Lecca L; Rook L. Rivista Italiana di Paleontologiae stratigrafia, 2007, 113(2): 287-297The fossils, aothough scarce and fragmentary,document the occurrence of a terrapin (Mauremyssp.) and the endemic Sardinian deer(Praemegaceros cazioti). Significant is the occurrenceof the terrapin because it is the youngestrepresentative of the genus Mauremys in thecentral Mediterranean area where it is extinct atpresent. The Late Pleistocene extinction ofMauremys in Italy follows the same pattern ofother Mediterranean reptiles, in being in somecases delayed on the islands. A comparison ofthe modern range of Mauremys and that of thepond turtle, Emys, as well as of their past rangesas evidenced by the fossil record, might suggestthat some sort of thermophily characterized theformer taxon and is responsible for its past andpresent distribution.2008040447亚 洲 白 垩 纪 一 种 新 的 具 最 深 体 腔 的 巨 型 蜥 脚类 恐 龙 = A New Gigantic Sauropod Dinosaurwith the Deepest Known Body Cavity from theCretaceous of Asia.
