JURASSIC WORLD and INDOMINUS REX What do you do when you want to boost visitor attendance to your dinosaur-dominated, Jurassic World theme park? Use DNA, from four different dinosaurs, and “in the Hammond lab” create something entirely new and fearsome. Then ... give the new creature a name which signifies its awesome power: Indominus rex. At least ... that’s how the story theme works in the 2015 film “Jurassic World.” So ... let’s travel back in time, to the age of the dinosaurs, and meet the four interesting creatures whose DNA led to this new and ferocious predator: Rugops; Carnotaurus; Giganotosaurus; Majungasaurus. If—contrary to plan—Indominus rex becomes a killing machine, we have to ask: Did she “inherit” that trait from her “ancestors?” Let’s examine the question, starting with Rugops (ROO-gops). What we know about this theropod, from a physical standpoint, comes from a single, nearly complete and fossilized skull. With its weak but gaping jaw and skull, Rugops—which means “wrinkle face”—is not a predator like the Cretaceous-Period Spinosaurus. Instead, Rugops is a natural-born scavenger, likely waiting in the wings for what’s left of a Spinosaurus-caught, Cretaceous-era fish known as Onchopristis. Living off the scraps of meals, killed by another creature, could be enough for a Rugops.

Basal abelisaurid and carcharodontosaurid theropods from the Lower Cretaceous Elrhaz Formation of Niger PAUL C. SERENO and STEPHEN L. BRUSATTE Sereno, P.C. and Brusatte, S.L. 2008. Basal abelisaurid and carcharodontosaurid theropods from the Lower Cretaceous Elrhaz Formation of Niger. Acta Palaeontologica Polonica 53 (1): 15–46. We report the discovery of basal abelisaurid and carcharodontosaurid theropods from the mid Cretaceous (Aptian– Albian, ca. 112 Ma) Elrhaz Formation of the Niger Republic. The abelisaurid, Kryptops palaios gen. et sp. nov., is repre− sented by a single individual preserving the maxilla, pelvic girdle, vertebrae and ribs. Several features, including a maxilla textured externally by impressed vascular grooves and a narrow antorbital fossa, clearly place Kryptops palaios within Abelisauridae as its oldest known member. The carcharodontosaurid, Eocarcharia dinops gen. et sp. nov., is repre− sented by several cranial bones and isolated teeth. Phylogenetic analysis places it as a basal carcharodontosaurid, similar to Acrocanthosaurus and less derived than Carcharodontosaurus and Giganotosaurus. The discovery of these taxa sug− gests that large body size and many of the derived cranial features of abelisaurids and carcharodontosaurids had already evolved by the mid Cretaceous. The presence of a close relative of the North American genus Acrocanthosaurus on Af− rica suggests that carcharodontosaurids had already achieved a trans−Tethyan distribution by the mid Cretaceous.

Fused and Vaulted Nasals of Tyrannosaurid Dinosaurs: Implications for Cranial Strength and Feeding Mechanics
Fused and vaulted nasals of tyrannosaurid dinosaurs: Implications for cranial strength and feeding mechanics ERIC SNIVELY, DONALD M. HENDERSON, and DOUG S. PHILLIPS Snively, E., Henderson, D.M., and Phillips, D.S. 2006. Fused and vaulted nasals of tyrannosaurid dinosaurs: Implications for cranial strength and feeding mechanics. Acta Palaeontologica Polonica 51 (3): 435–454. Tyrannosaurid theropods display several unusual adaptations of the skulls and teeth. Their nasals are fused and vaulted, suggesting that these elements braced the cranium against high feeding forces. Exceptionally high strengths of maxillary teeth in Tyrannosaurus rex indicate that it could exert relatively greater feeding forces than other tyrannosaurids. Areas and second moments of area of the nasals, calculated from CT cross−sections, show higher nasal strengths for large tyrannosaurids than for Allosaurus fragilis. Cross−sectional geometry of theropod crania reveals high second moments of area in tyrannosaurids, with resulting high strengths in bending and torsion, when compared with the crania of similarly sized theropods. In tyrannosaurids trends of strength increase are positively allomeric and have similar allometric expo− nents, indicating correlated progression towards unusually high strengths of the feeding apparatus. Fused, arched nasals and broad crania of tyrannosaurids are consistent with deep bites that impacted bone and powerful lateral movements of the head for dismembering prey. Key words: Theropoda, Carnosauria, Tyrannosauridae, biomechanics, feeding mechanics, computer modeling, com− puted tomography.

Although the tooth was Accepted 12 May, 2020 misidentified as a "Prodeinodon"-like megalosaurid theropod at the first time, detailed comparisons with known theropod dentition anatomy strongly indicate that this tooth belongs to an Acrocanthosaurus-like basal carcharodontosaurid theropod. This referral is supported by its combination of large size, ovoid-shaped cervix outline, mesial carina that does not reach the cervix, labially displaced distal carina and large number of denticles. This tooth is different from other carcharodontosaurid teeth from the same formation in several anatomical aspects (e.g., smaller overall size, presence of transverse lines adjacent to the distal carina, presence of interdenticular sulci in distal carina, denticle densities, crown basal ratio), indicating that carcharodontosaurid diversity in the Early Cretaceous of Korea could have been higher, although these differences may represent positional or individual variations. The presence of Acrocanthosaurus-like theropod teeth (e.g., "Prodeinodon", "Wakinosaurus") from early Cretaceous deposits (Valanginian-Cenomanian) of South Korea, Japan, Mongolia and China indicates that North American Acrocanthosaurus atokensis possibly represents a form that immigrated from the Asia.

FACT SHEET: Giganotosaurus
FACT SHEET: giganotosaurus NAME: GIGANOTOSAURUS (JIG-an-oh-toh-SAW-rus), “Giant Southern Lizard” SIZE: 45 feet long, 12 feet tall (the size of a locomotive), weighed 8 tons TYPE OF DIET: Carnivore (large dinosaurs) WHEN: Late Cretaceous period (100 million years ago) WHERE: Argentina (South America) When the fossilized skeleton of Giganotosaurus was discovered in 1995, many people got very excited. It was one of the largest known carnivores ever to walk the earth. Giganotosaurus means "giant southern lizard" because it was found in Argentina, South America. Only 70 percent of the skeleton was found, but it was enough to re-build this giant creature. It was about 45 feet long: that’s about the size of a locomotive. It was five feet longer than Tyrannosaurus rex and about two tons heavier. Giganotosaurus wasn’t a very intelligent dinosaur. Its brain was about the size of a banana. Giganotosaurus walked on two thick, powerful legs and had enormous jaws. Its teeth were 8 inches long and serrated like the edge of a saw. Giganotosaurus lived about 100 million years ago. Giganotosaurus may have hunted animals much larger than itself, such as the huge sauropod plant-eaters like Brontosaurus and Diplodocus. The skeleton of a 75 foot-long herbivore was found right next to the fossil of a Giganotosaurus. It had a long, skinny tail which was useful for balance. This means it could turn quickly while running and jumping. Its tail shot straight out behind it and was kept far off the ground. Several skeletons of Giganotosaurus were found together in the same place.

A Century of Spinosaurs - a Review and Revision of the Spinosauridae
View metadata, citation and similar papers at core.ac.uk brought to you by CORE provided by Queen Mary Research Online A century of spinosaurs - a review and revision of the Spinosauridae with comments on their ecology HONE David William Elliott1, * HOLTZ Thomas Richard Jnr2 1 School of Biological and Chemical Sciences, Queen Mary University of London, London, E1 4NS, UK 2 Department of Geology, University of Maryland, College Park, MD 20742 USA Abstract: The spinosaurids represent an enigmatic and highly unusual form of large tetanuran theropods that were first identified in 1915. A recent flurry of discoveries and taxonomic revisions of this important and interesting clade had added greatly to our knowledge, however, spinosaur body fossils are generally rare and most species are known from only limited skeletal remains. Their unusual anatomical adaptations to the skull, limbs and axial column all differ from other large theropods and point to an unusual ecological niche and a lifestyle intimately linked to water. Keywords: Theropoda, Megalosauroidea, Baryonychinae, Spinosaurinae, palaeoecology E-mail: [email protected] 1 Introduction The Spinosauridae is an enigmatic clade of large and carnivorous theropods from the Jurassic and Cretaceous that are known from both Gondwana and Laurasia (Holtz et al., 2004). Despite their wide temporal and geographic distribution, the clade is known primarily from teeth and the body fossil record is extremely limited (Bertin, 2010). As such, relatively little is known about this group of animals, although their unusual morphology with regard to skull shape, dentition, dorsal neural spines and other features mark them out as divergent from the essential bauplan of other non-tetanuran theropods (Fig 1).

Mapusaurus Roseae N
A new carcharodontosaurid (Dinosauria, Theropoda) from the Upper Cretaceous of Argentina Rodolfo A. CORIA CONICET, Museo Carmen Funes, Av. Córdoba 55, 8318 Plaza Huincul, Neuquén (Argentina) [email protected] Philip J. CURRIE University of Alberta, Department of Biological Sciences, Edmonton, Alberta T6G 2E9 (Canada) [email protected] Coria R. A. & Currie P. J. 2006. — A new carcharodontosaurid (Dinosauria, Theropoda) from the Upper Cretaceous of Argentina. Geodiversitas 28 (1) : 71-118. ABSTRACT A new carcharodontosaurid theropod from the Huincul Formation (Aptian- Cenomanian, Upper Cretaceous) of Neuquén Province, Argentina, is described. Approximately the same size as Giganotosaurus carolinii Coria & Salgado, 1995, Mapusaurus roseae n. gen., n. sp. is characterized by many features including a deep, short and narrow skull with relatively large triangular antorbital fossae, relatively small maxillary fenestra, and narrow, unfused rugose nasals. Mapu- saurus roseae n. gen., n. sp. has cervical neural spines and distally tapering epipo- physes, tall dorsal neural spines, central pleurocoels as far back as the first sacral vertebra, accessory caudal neural spines, stout humerus with poorly defined distal condyles, fused metacarpals, ilium with brevis fossa extending deeply into ischial peduncle, and femur with low fourth trochanter. Phylogenetic analysis indicates that Mapusaurus n. gen. shares with Carcharodontosaurus Stromer, 1931 and Giganotosaurus Coria & Salgado, 1995 several derived features that include narrow blade-like teeth with wrinkled enamel, heavily sculptured fa- cial bones, supraorbital shelf formed by a postorbital/palpebral complex, and a dorsomedially directed femoral head. Remains of Mapusaurus n. gen. were recovered from a bonebed where 100% of the identifiable dinosaur bones can KEY WORDS be assigned to this new genus.

Second Discovery of a Spinosaurid Tooth from the Sebayashi Formation (Lower Cretaceous), Kanna Town, Gunma Prefecture, Japan
群馬県立自然史博物館研究報告（21）：1－6,2017 1 Bull.Gunma Mus.Natu.Hist（. 21）：1－6,2017 Original Article Second discovery of a spinosaurid tooth from the Sebayashi Formation (Lower Cretaceous), Kanna Town, Gunma Prefecture, Japan 1 2 2 KUBOTA Katsuhiro, TAKAKUWA Yuji and HASEGAWA Yoshikazu 1Kanna Dinosaur Center: 51-2, Kagahara, Kanna, Tano, Gunma 370-1602, Japan ([email protected]) 2Gunma Museum of Natural History: 1674-1 Kamikuroiwa, Tomioka, Gunma 370-2345, Japan ([email protected]; [email protected]) Abstract： A fragment of an isolated tooth is described from the Lower Cretaceous Sebayashi Formation of the Sanchu Group. Its crown is almost round in cross section and shows distinctive flutes. Between the flutes, there are longitudinal finely granular structures. The distinctive carinae have poorly defined serrations. It is probably assigned as a spinosaurid theropod dinosaur and is the second report from Japan. This spinosaurid tooth is found from the higher stratigraphic horizon of the same formation than the first. The occurrences of spinosaurids from two horizons suggest that spinosaurids might have habituated this area during the deposit of the Sebayashi Formation. The dental comparison between Asian and other spinosaurids suggests that Asian spinosaurids may have unique dental characteristics and be different from any known spinosaurids, although the phylogenetic relationships between Asian and other spinosaurids (baryonychines and spinosaurines) are unclear. Key words: Dinosaur, Spinosauridae, Sebayashi Formation, Gunma Prefecture, Kanna Town Introduction Macro-sized and longitudinal ornamentation on the crown is characteristic in spinosaurids and had been called as crest, flute, A fragmentary dinosaur tooth was collected in a fossil- ridge, and striation (Fig.

Raptors in Action 1 Suggested Pre-Visit Activities
PROGRAM OVERVIEW TOPIC: Small theropods commonly known as “raptors.” THEME: Explore the adaptations that made raptors unique and successful, like claws, intelligence, vision, speed, and hollow bones. PROGRAM DESCRIPTION: Razor-sharp teeth and sickle-like claws are just a few of the characteristics that have made raptors famous. Working in groups, students will build a working model of a raptor leg and then bring it to life while competing in a relay race that simulates the hunting techniques of these carnivorous animals. AUDIENCE: Grades 3–6 CURRICULUM CONNECTIONS: Grade 3 Science: Building with a Variety of Materials Grade 3–6 Math: Patterns and Relations Grade 4 Science: Building Devices and Vehicles that Move Grade 6 Science: Evidence and Investigation PROGRAM ObJECTIVES: 1. Students will understand the adaptations that contributed to the success of small theropods. 2. Students will explore the function of the muscles used in vertebrate movement and the mechanics of how a raptor leg works. 3. Students will understand the function of the raptorial claw. 4. Students will discover connections between small theropod dinosaurs and birds. SUGGESTED PRE-VISIT ACTIVITIES UNDERstANDING CLADIstICS Animals and plants are often referred to as part of a family or group. For example, the dog is part of the canine family (along with wolves, coyotes, foxes, etc.). Scientists group living things together based on relationships to gain insight into where they came from. This helps us identify common ancestors of different organisms. This method of grouping is called “cladistics.” Cladistics is a system that uses branches like a family tree to show how organisms are related to one another.
