Despite its charismatic presence in pop culture and dinosaurian phylogenetic analyses, major aspects of the skeletal anatomy, taxonomy, ontogeny, and evolutionary relationships of this dinosaur remain unknown. Skeletons of this species were collected from the middle and lower part of the Kayenta Formation in the Navajo Nation in northern Arizona. Redescription of the holotype, referred, and previously undescribed specimens of Dilophosaurus wetherilli supports the existence of a single species of crested, large-bodied theropod in the Kayenta Formation. The parasagittal nasolacrimal crests are uniquely constructed by a small ridge on the nasal process of the premaxilla, dorsoventrally expanded nasal, and tall lacrimal that includes a posterior process behind the eye.

  • ABSTRACT Resurrecting Tyrannosaurus Rex Lauren E. Ammerman Director: Jennifer Good, Ph.D. After the First Successful Extraction
    ABSTRACT Resurrecting Tyrannosaurus rex Lauren E. Ammerman Director: Jennifer Good, Ph.D. After the first successful extraction of ancient DNA from a fossilized Quagga in 1984, the subsequent development of PCR (Polymerase Chain Reaction) technology opened up a plethora of possibilities in the field of molecular paleontology. Supplied with fragmented ancient genomes, some scientists acted as if the days of resurrecting dinosaurs were a few technical difficulties away. Theories surfaced on the possible applications of ancient DNA technology, and some, such as creating tactical dinosaurs for the U.S. military, were outrageous. A less ridiculous idea surfaced in the form of Michael Crichton’s Jurassic Park, published in 1990. Coupled with Steven Spielberg’s 1993 feature film adaption, the Jurassic Park series created a world in which genetically- engineered dinosaurs roamed once again as theme park attractions on a billionaire’s private island, and explored the possible outcomes of a “Jurassic Park” experiment. Jurassic Park ignited scientific debate over the technological feasibility, environmental impact, and ethical questions of a “Jurassic Park” experiment. This thesis continues that conversation by asking, could resurrecting a dinosaur be a productive environmental enterprise, other than a mere display of power over Nature? Focusing on Tyrannosaurus rex, this thesis combines a brief survey the current state of dinosaur genetic research, with analyses of rewilding with large predators, to discuss whether or not scientists should ever attempt to re-create a T. rex in the future.

  • Body-Size Evolution in the Dinosauria
    8 Body-Size Evolution in the Dinosauria Matthew T. Carrano Introduction The evolution of body size and its influence on organismal biology have received scientific attention since the earliest decades of evolutionary study (e.g., Cope, 1887, 1896; Thompson, 1917). Both paleontologists and neontologists have attempted to determine correlations between body size and numerous aspects of life history, with the ultimate goal of docu- menting both the predictive and causal connections involved (LaBarbera, 1986, 1989). These studies have generated an appreciation for the thor- oughgoing interrelationships between body size and nearly every sig- nificant facet of organismal biology, including metabolism (Lindstedt & Calder, 1981; Schmidt-Nielsen, 1984; McNab, 1989), population ecology (Damuth, 1981; Juanes, 1986; Gittleman & Purvis, 1998), locomotion (Mc- Mahon, 1975; Biewener, 1989; Alexander, 1996), and reproduction (Alex- ander, 1996). An enduring focus of these studies has been Cope’s Rule, the notion that body size tends to increase over time within lineages (Kurtén, 1953; Stanley, 1973; Polly, 1998). Such an observation has been made regarding many different clades but has been examined specifically in only a few (MacFadden, 1986; Arnold et al., 1995; Jablonski, 1996, 1997; Trammer & Kaim, 1997, 1999; Alroy, 1998). The discordant results of such analyses have underscored two points: (1) Cope’s Rule does not apply universally to all groups; and (2) even when present, size increases in different clades may reflect very different underlying processes. Thus, the question, “does Cope’s Rule exist?” is better parsed into two questions: “to which groups does Cope’s Rule apply?” and “what process is responsible for it in each?” Several recent works (McShea, 1994, 2000; Jablonski, 1997; Alroy, 1998, 2000a, 2000b) have begun to address these more specific questions, attempting to quantify patterns of body-size evolution in a phylogenetic (rather than strictly temporal) context, as well as developing methods for interpreting the resultant patterns.

  • The Origin and Evolution of the Dinosaur Infraorder Carnosauria*
    PALEONTOLOGICHESKIY ZHURNAL 1989 No. 4 KURZANOV S. M. THE ORIGIN AND EVOLUTION OF THE DINOSAUR INFRAORDER CARNOSAURIA* Paleontological Institute of the Academy of Sciences of the USSR Based on a revision of the systematic composition of the carnosaur families, a new diagram of the phylogenetic relationships within the infraorder is proposed. The question of carnosaurs cannot be considered to be resolved. Excluding the Triassic forms, carnosaurs in the broad or narrow sense have always been considered to be a group of theropods because they are only slightly different from them in fundamental features associated with large body size and a predatory lifestyle. The Late Triassic genera, such as Teratosaurus and Sinosaurus [33], were assigned to these on the basis of extremely meager material and without sufficient justification. This assignment has subsequently been rejected by most authors [13, 16, 17, 24, 25]. Huene [23] suggested that, along with the Sauropoda and Prosauropoda, the carnosaurs form a natural group Pachypodosauria, within which they are thought to be direct descendants of the prosauropods (the carnosaurs proceed directly from Teratosaurus through Magnosaurus). Studies of abundant cranial material (which actually belongs to Sellosaurus gracilis Huene) gave reason to think that the first species had been a prosauropod, whereas typical material (maxilla, ischium) belong to thecodonts from the family Poposauridae [24]. Huene’s diagram, which initially did not receive support, was widely propagated by the discovery of an unusual carnosaur Torvosaurus tanneri Galton et Jensen in the Upper Triassic deposits of Colorado [25]. The exceptionally plesiomorphic nature of some of its features, in the authors’ opinion, gave sufficient justification for removing them from the prosauropods.

At the advent of dinosaur paleontology fossil hunters like Gideon Mantell discovered some of the first dinosaurs like Iguanodon and Megalosaurus. Through new disciples like Georges Cuvier’s comparative anatomy lead early dinosaur paleontologist to reconstruct them like giant reptiles of absurd proportions. This lead to the formation of a new paradigm that prehistoric animals like dinosaurs existed and eventually went extinct.

  • FACT SHEET: Megalosaurus
    FACT SHEET: megalosaurus NAME: MEGALOSAURUS (MEG-ah-lo-SAW-rus), meaning: "Great Lizard" SIZE: 30 feet long, 10 feet tall (the size of a school bus), weighed 1 ton TYPE OF DIET: Carnivore (large sauropods, also a scavenger) WHEN: Early Jurassic period (181 - 169 million years ago) WHERE: England (United Kingdom) Megalosaurus lived about 181-169 million years ago. It was one the first dinosaur fossils ever discovered. A man named William Buckland first studied these ancient bones in England, and in 1824 he named the creature Megalosaurus, which means “great lizard”. He wrote the first scientific description of what would eventually be called a “dinosaur”. He only found pieces of a leg, shoulder, hip and jaw. From these pieces, he did his best to build the first picture of a dinosaur. And even though he didn’t have many bones to work with, he understood that Megalosaurus was a large, bipedal dinosaur. This means that it walked on two legs. Megalosaurus was a huge dinosaur. It grew up to 30 feet long, ten feet tall, and weighed about a ton. It had a strong, short neck and a large head. It had a thick, long tail, and heavy bones. Many paleontologists believe that it was clumsy walker. Its toes point inward and the prints seem to show that it wasn’t very agile. However, Megalosaurus could probably run very fast when it needed to. Megalosaurus was a carnivore, meaning that it hunted other animals for food. It had long, curved, serrated teeth that had jagged edges, like a saw.

  • The Dentition of Megalosaurid Theropods
    The dentition of megalosaurid theropods CHRISTOPHE HENDRICKX, OCTÁVIO MATEUS, and RICARDO ARAÚJO Hendrickx, C., Mateus, O., and Araújo, R. 2015. The dentition of megalosaurid theropods. Acta Palaeontologica Polo- nica 60 (3): 627–642. Theropod teeth are particularly abundant in the fossil record and frequently reported in the literature. Yet, the dentition of many theropods has not been described comprehensively, omitting details on the denticle shape, crown ornamentations and enamel texture. This paucity of information has been particularly striking in basal clades, thus making identification of isolated teeth difficult, and taxonomic assignments uncertain. We here provide a detailed description of the dentition of Megalosauridae, and a comparison to and distinction from superficially similar teeth of all major theropod clades. Megalosaurid dinosaurs are characterized by a mesial carina facing mesiolabially in mesial teeth, centrally positioned carinae on both mesial and lateral crowns, a mesial carina terminating above the cervix, and short to well-developed in- terdenticular sulci between distal denticles. A discriminant analysis performed on a dataset of numerical data collected on the teeth of 62 theropod taxa reveals that megalosaurid teeth are hardly distinguishable from other theropod clades with ziphodont dentition. This study highlights the importance of detailing anatomical descriptions and providing additional morphometric data on teeth with the purpose of helping to identify isolated theropod teeth in the future. Key words: Theropoda, Tetanurae, Megalosauridae, dentition, teeth, morphometry.

  • New Information on the Cranial Anatomy of Acrocanthosaurus Atokensis and Its Implications for the Phylogeny of Allosauroidea (Dinosauria: Theropoda)
    New Information on the Cranial Anatomy of Acrocanthosaurus atokensis and Its Implications for the Phylogeny of Allosauroidea (Dinosauria: Theropoda) Drew R. Eddy*¤, Julia A. Clarke¤ Department of Marine, Earth, and Atmospheric Sciences, North Carolina State University, Raleigh, North Carolina, United States of America Abstract Background: Allosauroidea has a contentious taxonomic and systematic history. Within this group of theropod dinosaurs, considerable debate has surrounded the phylogenetic position of the large-bodied allosauroid Acrocanthosaurus atokensis from the Lower Cretaceous Antlers Formation of North America. Several prior analyses recover Acrocanthosaurus atokensis as sister taxon to the smaller-bodied Allosaurus fragilis known from North America and Europe, and others nest Acrocanthosaurus atokensis within Carcharodontosauridae, a large-bodied group of allosauroids that attained a cosmopolitan distribution during the Early Cretaceous. Methodology/Principal Findings: Re-evaluation of a well-preserved skull of Acrocanthosaurus atokensis (NCSM 14345) provides new information regarding the palatal complex and inner surfaces of the skull and mandible. Previously inaccessible internal views and articular surfaces of nearly every element of the skull are described. Twenty-four new morphological characters are identified as variable in Allosauroidea, combined with 153 previously published characters, and evaluated for eighteen terminal taxa. Systematic analysis of this dataset recovers a single most parsimonious topology placing Acrocanthosaurus atokensis as a member of Allosauroidea, in agreement with several recent analyses that nest the taxon well within Carcharodontosauridae. Conclusions/Significance: A revised diagnosis of Acrocanthosaurus atokensis finds that the species is distinguished by four primary characters, including: presence of a knob on the lateral surangular shelf; enlarged posterior surangular foramen; supraoccipital protruding as a double-boss posterior to the nuchal crest; and pneumatic recess within the medial surface of the quadrate.
