Aptian–Albian) of Texas and Oklahoma
Reappraisal of the tribosphenidan mammals from the Trinity Group (Aptian–Albian) of Texas and Oklahoma BRIAN M. DAVIS and RICHARD L. CIFELLI Davis, B.M. and Cifelli, R.L. 2011. Reappraisal of the tribosphenidan mammals from the Trinity Group (Aptian–Albian) of Texas and Oklahoma. Acta Palaeontologica Polonica 56 (3): 441–462. The Trinity therians have long been the focus of attempts to reconstruct the evolutionary history of higher mammals, es− pecially in the context of the development of tribospheny. In this paper, we update the taxonomy of the tribosphenidan taxa known from the Trinity Group and establish with more confidence the premolar/molar count in each. Many isolated specimens can be referred to a specific tooth locus. Additional diversity is revealed within the Deltatheroida, with the de− scription of an additional species of Oklatheridium; Pappotherium is here considered a likely metatherian based on the in− ferred presence of four molars, while Holoclemensia is a basal eutherian (the opposite of some traditional interpretations). The remainder of the genera, Kermackia and Slaughteria, cannot be allied with either of the living groups of tribo− sphenidan mammals using the available data. We identify strong morphological diversity within this assemblage of stem taxa, including modifications to the traditional tribosphenic occlusal pattern in Kermackia. Mammalian evolution at the base of the tribosphenidan radiation was complex, and this underscores the need for caution when interpreting the mor− phology and relationships of taxa known by incomplete material. Key words: Tribosphenida, Metatheria, Eutheria, Deltatheroida, Trinity Group, Early Cretaceous. Brian M. Davis [[email protected]] and Richard L.

Texas 78711 ii ABSTRACT Regional differences in the porosity and permeability of the Edwards aquifer are related to three major depositional areas, the Maverick basin, the Devils River trend, and the San Marcos platform, that existed during Early Cretaceous time. The rocks of the Maverick basin are predominantly deep basinal deposits of dense, homogeneous mudstones of low primary porosity. Permeability is principally associated with cavernous voids in the upper part of the Salmon Peak Formation in the Maverick basin. The rocks of the Devils River trend are a complex of marine and supratidal deposits in the lower part and reefal or inter-reefal deposits in the upper part. Permeable zones, which occur in the upper part ofthe trend, are associated with collapse breccias and rudist reefs. -

Only two such giant “raptors” have been described from North America. Here, we describe a new giant dromaeosaurid, Dakotaraptor steini gen. et sp. nov., from the Hell Creek Formation of South Dakota. The discovery represents the first giant dromaeosaur from the Hell Creek Formation, and the most recent in the fossil record worldwide. A row of prominent ulnar papilli or “quill knobs” on the ulna is our first clear evidence for feather quills on a large dromaeosaurid forearm and impacts evolutionary reconstructions and functional morphology of such derived, typically flight-related features. -

Report 360 Aquifers of the Edwards Plateau Chapter 2
Chapter 2 Conceptual Model for the Edwards–Trinity (Plateau) Aquifer System, Texas Roberto Anaya1 Introduction The passage of Senate Bill 1 in 1997 established a renewed public interest in the State’s water resources not experienced since the drought of the 1950s. Senate Bill 1 of 1999 and Senate Bill 2 of 2001 provided state funding to initiate the development of groundwater availability models for all of the major and minor aquifers of Texas. The development and management of Groundwater Availability Models (GAMs) has been tasked to the Texas Water Development Board (TWDB) to provide reliable and timely information on the State’s groundwater resources. TWDB staff is currently developing a GAM for the Edwards–Trinity (Plateau) aquifer. An essential task in the design of a numerical groundwater flow model is the development of a conceptual model. The conceptual model is a generalized description of the aquifer system that defines boundaries, hydrogeologic parameters, and hydrologic stress variables. The conceptual model helps to compile and organize field data and to simplify the real-world aquifer flow system into a graphical or diagrammatical representation while retaining the complexity needed to adequately reproduce the system behavior (Anderson and Woessner, 1992). The first step in the development of a conceptual model is to delineate the study area and form an understanding of its physical landscape with regard to the physiography, climate, and geology. Another early step also involves the research and investigation of previous aquifer studies. Intermediate steps bring together all of the information for establishing the hydrogeologic setting which consists of the hydrostratigraphy, structural geometry, hydraulic properties, water levels and regional groundwater flow, recharge, interactions between surface water and groundwater, well discharge, and water quality. -
The Ontogenetic Osteohistology of Tenontosaurus Tilletti
The Ontogenetic Osteohistology of Tenontosaurus tilletti Sarah Werning*¤ Department of Zoology and Sam Noble Oklahoma Museum of Natural History, University of Oklahoma, Norman, Oklahoma, United States of America Abstract Tenontosaurus tilletti is an ornithopod dinosaur known from the Early Cretaceous (Aptian-Albian) Cloverly and Antlers formations of the Western United States. It is represented by a large number of specimens spanning a number of ontogenetic stages, and these specimens have been collected across a wide geographic range (from central Montana to southern Oklahoma). Here I describe the long bone histology of T. tilletti and discuss histological variation at the individual, ontogenetic and geographic levels. The ontogenetic pattern of bone histology in T. tilletti is similar to that of other dinosaurs, reflecting extremely rapid growth early in life, and sustained rapid growth through sub-adult ontogeny. But unlike other iguanodontians, this dinosaur shows an extended multi-year period of slow growth as skeletal maturity approached. Evidence of termination of growth (e.g., an external fundamental system) is observed in only the largest individuals, although other histological signals in only slightly smaller specimens suggest a substantial slowing of growth later in life. Histological differences in the amount of remodeling and the number of lines of arrested growth varied among elements within individuals, but bone histology was conservative across sampled individuals of the species, despite known paleoenvironmental differences between the Antlers and Cloverly formations. The bone histology of T. tilletti indicates a much slower growth trajectory than observed for other iguanodontians (e.g., hadrosaurids), suggesting that those taxa reached much larger sizes than Tenontosaurus in a shorter time. -
