EXHIBITION FOR HIRE THE DINOSAURS ARE BACK! THE DINOSAURS ARE BACK! In partnership with Emilio’s Creations, Universeum proudly presents the unique dinosaur exhibition “The dinosaurs are back”. The latest scientific discoveries are summarised in a spectacular visitor experience with 16 life-size dinosaurs that move and make noises. Ten of them are feathered in accordance with recent research. The exhibition for hire comprises eight different species set in a prehistoric forest landscape with trees and plants from that specific era. Included is the world’s largest known land predator, theSpinosaurus , at 14 metres long and five metres tall. Also on display are the four-metre tall and fully feathered Therizinosaurus and the legendary Tyrannosaurus rex, together with a feathered juvenile.

Despite a diverse Asian representation with remarkable growth in recent years, the North American record of the clade remains poor, with only one controversial species—Troodon formosus—presently known from substantial skeletal remains. Methodology/Principal Findings: Here we report a gracile new troodontid theropod—Talos sampsoni gen. et sp. nov.— from the Upper Cretaceous Kaiparowits Formation, Utah, USA, representing one of the most complete troodontid skeletons described from North America to date. Histological assessment of the holotype specimen indicates that the adult body size of Talos was notably smaller than that of the contemporary genus Troodon. Phylogenetic analysis recovers Talos as a member of a derived, latest Cretaceous subclade, minimally containing Troodon, Saurornithoides, and Zanabazar.

Theropod Teeth from the Upper Maastrichtian Hell Creek Formation “Sue” Quarry: New Morphotypes and Faunal Comparisons
Theropod teeth from the upper Maastrichtian Hell Creek Formation “Sue” Quarry: New morphotypes and faunal comparisons TERRY A. GATES, LINDSAY E. ZANNO, and PETER J. MAKOVICKY Gates, T.A., Zanno, L.E., and Makovicky, P.J. 2015. Theropod teeth from the upper Maastrichtian Hell Creek Formation “Sue” Quarry: New morphotypes and faunal comparisons. Acta Palaeontologica Polonica 60 (1): 131–139. Isolated teeth from vertebrate microfossil localities often provide unique information on the biodiversity of ancient ecosystems that might otherwise remain unrecognized. Microfossil sampling is a particularly valuable tool for doc- umenting taxa that are poorly represented in macrofossil surveys due to small body size, fragile skeletal structure, or relatively low ecosystem abundance. Because biodiversity patterns in the late Maastrichtian of North American are the primary data for a broad array of studies regarding non-avian dinosaur extinction in the terminal Cretaceous, intensive sampling on multiple scales is critical to understanding the nature of this event. We address theropod biodiversity in the Maastrichtian by examining teeth collected from the Hell Creek Formation locality that yielded FMNH PR 2081 (the Tyrannosaurus rex specimen “Sue”). Eight morphotypes (three previously undocumented) are identified in the sample, representing Tyrannosauridae, Dromaeosauridae, Troodontidae, and Avialae. Noticeably absent are teeth attributed to the morphotypes Richardoestesia and Paronychodon. Morphometric comparison to dromaeosaurid teeth from multiple Hell Creek and Lance formations microsites reveals two unique dromaeosaurid morphotypes bearing finer distal denticles than present on teeth of similar size, and also differences in crown shape in at least one of these. These findings suggest more dromaeosaurid taxa, and a higher Maastrichtian biodiversity, than previously appreciated.

A New Raptorial Dinosaur with Exceptionally Long Feathering Provides Insights Into Dromaeosaurid flight Performance
ARTICLE Received 11 Apr 2014 | Accepted 11 Jun 2014 | Published 15 Jul 2014 DOI: 10.1038/ncomms5382 A new raptorial dinosaur with exceptionally long feathering provides insights into dromaeosaurid flight performance Gang Han1, Luis M. Chiappe2, Shu-An Ji1,3, Michael Habib4, Alan H. Turner5, Anusuya Chinsamy6, Xueling Liu1 & Lizhuo Han1 Microraptorines are a group of predatory dromaeosaurid theropod dinosaurs with aero- dynamic capacity. These close relatives of birds are essential for testing hypotheses explaining the origin and early evolution of avian flight. Here we describe a new ‘four-winged’ microraptorine, Changyuraptor yangi, from the Early Cretaceous Jehol Biota of China. With tail feathers that are nearly 30 cm long, roughly 30% the length of the skeleton, the new fossil possesses the longest known feathers for any non-avian dinosaur. Furthermore, it is the largest theropod with long, pennaceous feathers attached to the lower hind limbs (that is, ‘hindwings’). The lengthy feathered tail of the new fossil provides insight into the flight performance of microraptorines and how they may have maintained aerial competency at larger body sizes. We demonstrate how the low-aspect-ratio tail of the new fossil would have acted as a pitch control structure reducing descent speed and thus playing a key role in landing. 1 Paleontological Center, Bohai University, 19 Keji Road, New Shongshan District, Jinzhou, Liaoning Province 121013, China. 2 Dinosaur Institute, Natural History Museum of Los Angeles County, 900 Exposition Boulevard, Los Angeles, California 90007, USA. 3 Institute of Geology, Chinese Academy of Geological Sciences, 26 Baiwanzhuang Road, Beijing 100037, China. 4 University of Southern California, Health Sciences Campus, BMT 403, Mail Code 9112, Los Angeles, California 90089, USA.

A Comparison of Flight Potential Among Small-Bodied Paravians
Chapter 11 High Flyer or High Fashion? A Comparison of Flight Potential among Small-Bodied Paravians T. ALEXANDER DECECCHI,1 HANS C.E. LARSSON,2 MICHAEL PITTMAN,3 AND MICHAEL B. HABIB4 ABSTRACT The origin of flight in birds and its relationship to bird origins itself has achieved something of a renaissance in recent years, driven by the discovery of a suite of small-bodied taxa with large pen- naceous feathers. As some of these specimens date back to the Middle Jurassic and predate the earli- est known birds, understanding how these potential aerofoil surfaces were used is of great importance to answering the question: which came first, the bird or the wing? Here we seek to address this question by directly comparing key members of three of the major clades of paravians: anchiorni- thines, Microraptor and Archaeopteryx across their known size classes to see how they differ in terms of major flight-related parameters (wing loading; disc loading; specific lift; glide speed; takeoff poten- tial). Using specimens with snout to vent length (SVL) ranging from around 150 mm to 400 mm and mass ranging from approximately 130 g to 2 kg, we investigated patterns of inter- and intraspe- cific changes in flight potential. We find that anchiornithines show much higher wing- and disc- loading values and correspondingly high required minimum glide and takeoff speeds, along with lower specific lift and flapping running outputs suggesting little to no flight capability in this clade. In contrast, we see good support for flight potential, either gliding or powered flight, for all size classes of both Microraptor and Archaeopteryx, though there are differing patterns of how this shifts ontogenetically.

Dinosaurs put all colored birds' eggs in one basket, evolutionarily speaking 31 October 2018 red and blue, to create all of the various egg colors, spots, and speckles. Wiemann and her colleagues analyzed 18 fossil dinosaur eggshell samples from around the world, using non-destructive laser microspectroscopy to test for the presence of the two eggshell pigments. They found them in eggshells belonging to Eumaniraptoran dinosaurs, which include small, carnivorous dinosaurs such as Velociraptor. Fossil theropod dinosaur egg (front), with corvid eggs in a nest.

An Evaluation of Flapping-Based Locomotory Hypotheses in Bird
The wings before the bird: an evaluation of flapping-based locomotory hypotheses in bird antecedents T. Alexander Dececchi1, Hans C.E. Larsson2 and Michael B. Habib3,4 1 Department of Geological Sciences, Queens University, Kingston, Ontario, Canada 2 Redpath Museum, McGill University, Montreal, Quebec, Canada 3 Keck School of Medicine of USC, Department of Cell and Neurobiology, University of Southern California, Los Angeles, California, United States 4 Dinosaur Institute, Natural History Museum of Los Angeles, Los Angeles, CA, United States ABSTRACT Background: Powered flight is implicated as a major driver for the success of birds. Here we examine the effectiveness of three hypothesized pathways for the evolution of the flight stroke, the forelimb motion that powers aerial locomotion, in a terrestrial setting across a range of stem and basal avians: flap running, Wing Assisted Incline Running (WAIR), and wing-assisted leaping. Methods: Using biomechanical mathematical models based on known aerodynamic principals and in vivo experiments and ground truthed using extant avians we seek to test if an incipient flight stroke may have contributed sufficient force to permit flap running, WAIR, or leaping takeoff along the phylogenetic lineage from Coelurosauria to birds. Results: None of these behaviours were found to meet the biomechanical threshold requirements before Paraves. Neither was there a continuous trend of refinement for any of these biomechanical performances across phylogeny nor a signal of universal applicability near the origin of birds. None of these flap-based locomotory models appear to have been a major influence on pre-flight character acquisition such as pennaceous feathers, suggesting non-locomotory behaviours, and less Submitted 23 January 2016 stringent locomotory behaviours such as balancing and braking, played a role in Accepted 27 May 2016 the evolution of the maniraptoran wing and nascent flight stroke.

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.

American Museum Novitates
AMERICAN MUSEUM NOVITATES Number 3899, 44 pp. April 26, 2018 A Second Specimen of Citipati osmolskae Associated with a Nest of Eggs from Ukhaa Tolgod, Omnogov Aimag, Mongolia MARK A. NORELL,1, 2 AMY M. BALANOFF,1, 3 DANIEL E. BARTA,1, 2 AND GREGORY M. ERICKSON1, 4 ABSTRACT Adult dinosaurs preserved attending their nests in brooding positions are among the rarest vertebrate fossils. By far the most common occurrences are members of the dinosaur group Oviraptorosauria. The first finds of these were specimens recovered from the Djadokhta Forma- tion at the Mongolian locality of Ukhaa Tolgod and the Chinese locality of Bayan Mandahu. Since the initial discovery of these specimens, a few more occurrences of nesting oviraptors have been found at other Asian localities. Here we report on a second nesting oviraptorid specimen (IGM 100/1004) sitting in a brooding position atop a nest of eggs from Ukhaa Tolgod, Omnogov, Mongolia. This is a large specimen of the ubiquitous Ukhaa Tolgod taxon Citipati osmolskae. It is approximately 11% larger based on humeral length than the original Ukhaa Tolgod nesting Citipati osmolskae specimen (IGM 100/979), yet eggshell structure and egg arrangement are identical. No evidence for colonial breeding of these animals has been recovered. Reexamination of another “nesting” oviraptorosaur, the holotype of Oviraptor philoceratops (AMNH FARB 6517) indicates that in addition to the numerous partial eggs associated with the original skeleton that originally led to its referral as a protoceratopsian predator, there are the remains of a tiny theropod. This hind limb can be provisionally assigned to Oviraptoridae. It is thus at least possible that some of the eggs associated with the holotype had hatched and the perinates had not left the nest.

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.
