Stable Oxygen Isotope Chemostratigraphy and Paleotemperature Regime of Mosasaurs at Bentiaba, Angola

Email: [email protected] Manuscriptreceived:2June2014,accepted:6January2015 Abstract Stable oxygen isotope values of inoceramid marine bivalve shells recovered from Bentiaba, Angola, are utilised as a proxy for paleotemperatures during the Late Cretaceous development of the African margin of the South Atlantic Ocean. The d18O values derived from inoceramids show a long-term increase from –3.2‰ in the Late Turonian to values between –0.8 and –1.8‰ in the Late Campanian. Assuming a constant oceanic d18Ovalue,an∼2‰ increase may reflect cooling of the shallow marine environment at Bentiaba by approximately 10°. Bentiaba values are offset by about +1‰ from published records for bathyal Inoceramus at Walvis Ridge. This offset in d18O values suggests a temperature difference of ∼5° between coastal and deeper water offshore Angola. -
Russellosaurus Coheni N. Gen., N. Sp., a 92 Million-Year-Old Mosasaur from Texas (USA), and the Definition of the Parafamily Russellosaurina

Bell Jr.2 1 Shuler Museum of Paleontology, Southern Methodist University, Dallas, Texas 75275, USA. 2 Guadalupe Mountains National Park, Salt Flat, Texas 79847, USA. * Corresponding author. Email: [email protected] Manuscript received: November 2004; accepted: January 2005 Abstract A new mosasaur, Russellosaurus coheni, is described from the Collignoniceras woollgari Zone (lower Middle Turonian) at Cedar Hill, Dallas County, Texas. At approximately 92 Ma, it is the oldest well-preserved mosasaur skull from North America. It possesses characters diagnostic of Plioplatecarpinae but retains numerous plesiomorphies as well. Phylogenetic analysis indicates a close relationship with Yaguarasaurus columbianus, and these two, together with Tethysaurus nopcsai, form a clade that occupies a position basal to the divergence of the subfamilies Tylosaurinae and Plioplatecarpinae. Russellosaurus coheni is proposed as the nominal taxon of a new mosasaur clade, parafamily taxon novum Russellosaurina, which includes Plioplatecarpinae, Tylosaurinae, their common ancestor and all descendants. Tethysaurus retains a plesiopedal limb and girdle morphology, and along with Russellosaurus and Yaguarasaurus, cranial plesiomorphies. Dallasaurus turneri, a temporally and geographically sympatric plesiopedal mosasaur, occupies a basal position within Mosasaurinae. This phyletic arrangement confirms that marine adaptations, such as development of paddle-like limbs, occurred independently in at least two lineages of mosasaurs, once within Mosasaurinae and once within Russellosaurina. Keywords: Mosasaur, Plioplatecarpinae, Tethysaurus, Turonian, Yaguarasaurus Introduction knowledge of the early evolutionary history of the group. -
Allometric Growth in the Skull of Tylosaurus Proriger (Squamata: Mosasauridae) and Its Taxonomic Implications Robert F
Vertebrate Anatomy Morphology Palaeontology 6:75–90 75 ISSN 2292-1389 Allometric growth in the skull of Tylosaurus proriger (Squamata: Mosasauridae) and its taxonomic implications Robert F. Stewart1 and Jordan C. Mallon2,* 1Department of Earth Sciences, Carleton University, Ottawa, Ontario, Canada, K1S 5B6; [email protected] 2Palaeobiology, Canadian Museum of Nature, PO Box 3223, Station D, Ottawa, Ontario, Canada, K1P 6P4; [email protected] Abstract: Ontogeny—the growth and development of an organism—is among the more poorly understood aspects of the life history of mosasaurs, largely owing to a dearth of fossil material from young individuals. We describe the par- tial and nearly complete skulls of two subadult individuals of the mosasaurid Tylosaurus proriger from the upper Smoky Hills Chalk Member of the Niobrara Formation (upper Santonian) in Kansas. We include the more complete of the two specimens in an allometric analysis to better understand proportional changes in the skull through growth. Although our small sample size produces several instances of ‘soft isometry’, we recover the length of the edentulous rostrum as significantly negatively allometric, and quadrate height as significantly positively allometric. In light of our findings, we consider the question of whether T. kansasensis represents an immature ontogimorph of T. nepaeolicus, and find substan- tive evidence to reject this hypothesis. INTRODUCTION Seaway of North America (Williston 1898; Russell 1967; Everhart 2017). These are among the smallest skulls known Mosasauridae is a clade of carnivorous, mostly marine for the species, and they help to elucidate the allometric reptiles known from Upper Cretaceous deposits world- changes undergone by T. proriger through life. -

The specimen comprises a fragmentary skull and parts of the mandibles. Some anatomical features suggest a juvenile animal. The skull possesses a rostral tuberosity on the premaxilla, as well as a combination of features known from different mosasaur genera, like its frontopremaxillary suture situated caudal to the external naris, its prefrontal and postorbitofrontal being in contact lateral to the orbit, associated with the supra- and infrastapedial processes of its quadrate which almost contact one another. Despite being clearly distinct from any hitherto described mosasaur, the affinities of this specimen with other mosasaurs remain obscure, not only because of incompleteness, but also because of the poorly understood biological significance of the characters used for the classification of Mosasauridae. -

A Late Cretaceous Mosasaur from North-Central New Mexico
New Mexico Geological Society Guidebook, 46th Field Conference, Geology of the Santa Fe Region, 1995 257 A LATE CRETACEOUS MOSASAUR FROM NORTH-CENTRAL NEW MEXICO SPENCER G. LUCASl, ANDREW B. HECKERT2 and BARRY S. KUES2 New Mexico Museum of Natural History and Science, 1801 Mountain Road N.W., Albuquerque, New Mexico 87104; 2Department of Earth and Planetary Sciences, University of New Mexico, Albuquerque, New Mexico 87l31-1116 Abstract-We describe a partial vertebral column of a mosasaur identified as cf. Tylosaurus sp. from the lower Niobrara interval of the Mancos Shale south of Galisteo in Santa Fe County, New Mexico. Invertebrate fossils collected from the same horizon include the inoceramids cf. Inoceramus (Cremnoceramus) deformis and cf. Inoceramus (Platyceramus ) platinus and dense growths of the oyster Pseudoperna congesta. They suggest a Coniacian age. This is the oldest documented mosasaur from New Mexico. INTRODUCTION more, comparison of NMMNH P-22142 to Williston's (1898) plates Mosasaurs were marine lizards of the Late Cretaceous that first ap shows that in Tylosaurus the rib articulations on the dorsal vertebrae are peared during the Cenomanian (Russell, 1967, 1993). Although marine large, dorsally positioned and circular in cross section. NMMNH P-22142 Upper Cretaceous strata are widely exposed in New Mexico, the fossil is also very similar to specimens of Tylosaurus proriger illustrated by record of mosasaurs from the state is limited to a handful of documented Williston (1898, pIs. 62, 65, 72) in that no traces of a zygosphene occurrences (Lucas and Reser, 1981; Hunt and Lucas, 1993). Here, we zygantrum articulation can be seen on any of the vertebrae, and the neu add to this limited record notice of incomplete remains of a mosasaur ral spines are very long antero-posteriorly so that their edges almost meet.
