“…Aigialosaurus dalmaticus (Kramberger 1892) and Opetiosaurus bucchichi (Kornhuber 1901) were found on the island of Hvar, Croatia (Isola di Lesina), whereas Carsosaurus marchesetti (Kornhuber 1893) and "the Trieste aigialosaur" deBraga 1992, currently being described by A. Palci (personal communication, 2005)) were found near to Komen, Slovenia. In addition to these specimens, a number of partial specimens have been assigned to the "Aigialosauridae" including Haasiosaurus (= Haasia) gittelmani from the Cenomanian of Israel (Polcyn et al 1999), Dallasaurus turneri from the Turonian of Texas , and a partial specimen from the Turonian of Mexico (Buchy et al 2005).…”

Redescription of the type and only specimen of Aigialosaurus dalmaticus (BSP 1902II501), an "aigialosaurian" squamate from the Cenomanian-Turonian of Hvar, Croatia, and, at the time of collection, the Italian island of Lesina, indicates that previous reviews of the specimen include erroneous anatomical interpretations. The type specimen presents a new and unique pelvic anatomy: the ilium of A. dalmaticus is an elongate element with well-developed anterior and posterior iliac processes. A scenario is presented for mosasaurid pelvic evolution, whereby the anteriorly elongate and dorsally directed ilium of mosasauroids is not derived from the forward rotation of the posterior iliac process, but rather the reduction of that process and the elaboration of the anterior iliac process. Recent phylogenetic analysis of Mosasauroidea finds A. dalmaticus to be the sistergroup to Opetiosaurus bucchichi and all other mosasaurids and "aigialosaurs." We examine the character state assignments for A. dalmaticus in that study and refute those assignments owing to the absence of preservation of all four characters states found to separate A. dalmaticus from O. bucchichi. Résumé: Une nouvelle description du spécimen type et unique spécimen connu d'Aigialosaurus dalmaticus (BSP 1902II501), un squamate « aigialosaure » du Cénomanien-Turonien de Hvar (Croatie) et, au moment de son pré-lèvement, de l'île italienne de Lésina, indique que les examens antérieurs de ce spécimen comprennent des interpréta-tions anatomiques erronées. Le spécimen type présente une anatomie pelvienne nouvelle et unique : l'ilium d'A. dalmaticus consiste en un élément allongé comportant des processus iliaques antérieurs et postérieurs bien développés. Un scénario d'évolution du pelvis des Mosasauridés est présenté selon lequel l'ilium antérieurement allongé et dorsalement orienté des mosasauroïdes n'est pas dérivé de la rotation vers l'avant du processus iliaque postérieur, mais plutôt de la réduction de ce processus et de l'élaboration du processus iliaque antérieur. Une analyse phylogénétique récente des Mosasauroïdés établit qu'A. dalmaticus est le groupe-frère d'Opetiosaurus bucchichi et de tous les autres mosasaurides et « aigialosaures ». La présente étude se penche sur les attributions des états des caractères pour A. dalmaticus et les réfute en raison de la non-préservation de tous les états des caractères, au nombre de quatre, qui distinguent A. dalmaticus d'O. bucchichi.

“…Limbed snakes, which were exclusively known from Northern and Southern margins of the Mediterranean Tethys, became known intercontinentally in the Turonian (Gardner and Cifelli, 1999;Rage and Werner, 1999;Caldwell and Albino, 2001). Mosasauroids, also exclusively known from Europe in the Cenomanian, increase in size and distribution and by the mid-Turonian could be found in Africa, Europe, and North and South America (Von Loh and Bell, 1998;Bardet et al, 2003Bardet et al, , 2008Buchy et al, 2005;Schulp et al, 2008;Smith and Buchy, 2008;Longrich, 2016).…”

Spatiotemporal Distributions of Non-ophidian Ophidiomorphs, With Implications for Their Origin, Radiation, and Extinction

Non-ophidian ophidiomorphs, colloquially referred to as 'dolichosaurs,' are small-bodied aquatic lizards that lived in shallow seaways, rivers, and reef environments during the Late Cretaceous. Preservational, geographic, and taphonomic biases in this group make trends in biodiversity difficult to assess. This is exemplified by the fact that the majority of the described species are monotypic and known only from single specimens, imparting very little information on morphological or spatial variation. Here we present a revision of the spatial and temporal distributions of non-ophidian ophidiomorph lizards ('dolichosaurs') from Cretaceous sediments worldwide. The fossil record of dolichosaurs begins in the Valanginian (Early Cretaceous). The late Early Cretaceous records are sparse but suggest a wide geographic distribution spanning the Tethys and Western Pacific. This is followed by a dense Cenomanian record from Tethyan and British deposits, and rarer specimens from North America. Though there is a substantial drop in the number of specimens recorded from the Turonian-Maastrichtian, these rare occurrences represent the largest geographical distribution of dolichosaurs: spanning Europe, North America, and South America before going extinct during the end-Cretaceous mass extinction. These occurrences indicate that ophidiomorphs most likely originated in the Jurassic Tethys and continued to radiate spatially and phylogenetically until the end of the Mesozoic, showing much more temporally and environmentally diverse patterns than previously indicated.

Cretaceous δ¹³C stratigraphy and the age of dolichosaurs and early mosasaurs

Sediments in north-central Texas, ranging in age from >117 to 85 Ma, represent a variety of terrestrial and marine depositional settings. Isotopic analyses of wood fragments found throughout the section allow correlation to the standard secular marine 6 13 C curve because of characteristic peaks at the Aptian-Albian and Cenomanian-Turonian boundaries. Consistency of the north-central Texas 5 13 C curve with the marine standard facilitates correlation among non-marine and marine environments on a global scale. Radiometrically dated ammonite zones recognised in Texas provide calibration for the Cenomanian and Turonian portions of the section. Cenomanian and Turonian sediments in north-central Texas preserve the oldest (96 Ma) and the youngest (<85 Ma) well-documented Coniasaurus, a dolichosaur also known from the southern North Sea Basin during that interval. Haasiasaurus, the oldest known well-documented early mosasaur, is found at 'Ein Yabrud, Israel (98 Ma), followed by other poorly dated Cenomanian taxa from the eastern Mediterranean region, and then by Dallasaurus turneri and Russellosaurus coheni in Texas (92 Ma) andTethysaurus (90.5 Ma) in Morocco. Neither shifts in 6 13 C nor large-scale sea level change seem to have influenced dolichosaur or mosasaur evolution in substantial ways during the Cenomanian and Turonian stages.
