The tracks are preserved in the Helvetiafjellet For- mation (Barremian). A sedimentological characterization of the site indicates that the tracks formed on a beach/margin of a lake or interdistributary bay, and were preserved by flooding. In addition to the two imprints already known from the site, we describe at least 34 additional, pre- viously unrecognized pes and manus prints, including one trackway. Two pes morphotypes and one manus morphotype are recognized. Given the range of morphological variation and the pres- ence of manus tracks, we reinterpret all the prints as being from an ornithopod rather than a thero- pod, as previously described. We assign the smaller (morphotype A, pes; morphotype B, manus) to Caririchnium billsarjeanti. The larger (morphotype C, pes) track is assigned to Caririchnium sp., differing in size and interdigital angle from the two described ichnospecies C. burreyi and C. bill- sarjeanti. The occurrence of a quadrupedal, small to medium-sized ornithopod in Svalbard is puz- zling, considering the current palaeogeographical reconstructions and that such dinosaur tracks have mainly been described from Europe but not North America.

LOCKLEY1*, LIDA XING2, JEREMY A. F. LOCKWOOD3 and STUART POND3 1Dinosaur Trackers Research Group, University of Colorado at Denver, CB 172, PO Box 173364, Denver, CO 80217-3364, USA 2School of the Earth Sciences and Resources, China University of Geosciences, Beijing 100083, China 3Ocean and Earth Science, National Oceanography Centre, University of Southampton, Southampton SO14 3ZH, UK Received 30 January 2014; revised 12 February 2014; accepted for publication 13 February 2014 Trackways of ornithopods are well-known from the Lower Cretaceous of Europe, North America, and East Asia. For historical reasons, most large ornithopod footprints are associated with the genus Iguanodon or, more generally, with the family Iguanodontidae. Moreover, this general category of footprints is considered to be sufficiently dominant at this time as to characterize a global Early Cretaceous biochron. However, six valid ornithopod ichnogenera have been named from the Cretaceous, including several that are represented by multiple ichnospecies: these are Amblydactylus (two ichnospecies); Caririchnium (four ichnospecies); Iguanodontipus, Ornithopodichnus originally named from Lower Cretaceous deposits and Hadrosauropodus (two ichnospecies); and Jiayinosauropus based on Upper Cretaceous tracks. It has recently been suggested that ornithopod ichnotaxonomy is oversplit and that Caririchnium is a senior subjective synonym of Hadrosauropodus and Amblydactylus is a senior subjective synonym of Iguanodontipus. Although it is agreed that many ornithopod tracks are difficult to differentiate, this proposed synonymy is questionable because it was not based on a detailed study of the holotypes, and did not consider all valid ornithopod ichnotaxa or the variation reported within the six named ichnogenera and 11 named ichnospecies reviewed here.

Accepted: 2021-05-11. Abstract.—This manuscript provides an updated overview of the knowledge about Mexico's hadrosaurs through the critical review of 175 publications between 1913 and 2019, which report osteological, icnological, tegumentary, dental and oological remains of these organisms. The data were synthesized and analyzed using traditional statistical methods, accumulation curves and sampling efforts. In addition, a catalogue of 166 paleontological sites belonging to 18 geological units is provided, whose ages are between the Albian and the Maastrichtian, in the states of Baja California, Sonora, Chihuahua, Coahuila, Puebla and Michoacán. The data collected recognize a comparatively low taxonomic diversity with respect to the rest of North America, even though the study of these dinosaurs began systematically since the 80's in Mexico. Only five species have been described from bony remains and a single icnospecies, whereas other remains have been only vaguely identified. The review of the history of the study of hadrosaurs in Mexico, as well as the curves of the corresponding sampling effort, suggest that these dinosaurs were diverse and abundant in this country and distinct from the rest of America. Key words.— Cretaceous, bone remains, fossil record, ichnites. Resumen.— Este trabajo ofrece un panorama actualizado sobre los hadrosaurios de México a través de la revisión crítica de 175 publicaciones aparecidas entre 1913 y 2019, donde se reportan restos de naturaleza ósea, icnológica, tegumentaria, dental y oológica de estos organimos.

Para este fin, será necesario disponer de modelos virtuales del sistema motor (es decir, el pie, la pierna, etc.) y del sustrato sobre el que el dinosaurio se mueve. Ambos tipos de modelos pueden inferirse, de manera aproximada, a partir de restos fósiles: huesos para los primeros e icnitas (huellas fosilizadas) para los segundos. Por supuesto, existen importantes retos en estos modelos, por ejemplo, el hecho de que un grupo de huesos fósiles (posiblemente incompleto y deteriorado) está muy alejado de un animal articulado que camina, el cual no sólo dispone de huesos y articulaciones, sino también carne, tendones, piel, garras, etc.

  • Dinosaur Tracks 2011
    The Early Cretaceous (late Berriasian) Bückeberg Formation in the southern Lower Saxony Basin, to Annette Richter, Mike Reich (Eds.) the west and to the south of Hannover, yields abundant and diverse dinosaur tracks, known since the late 1870s. After a few decades of pioneering and discovery, this area was scientifi cally neglected for a long time concerning dinosaur tracks and tracksites, and only single sporadic fi nds were reported in the second half of the 20th century. During 2007 and 2008, a new tracksite was discovered in Dinosaur Tracks 2011 Obernkirchen, yielding an astonishing amount of new and well-preserved dinosaur tracks, cared for by the Hannover State Museum and its cooperational partners. The present volume contains the An International Symposium, abstracts of lectures and posters presented during the Dinosaur Track Symposium 2011 as well as Obernkirchen, April 14-17, 2011 excursion and collection guides. On behalf of the Schaumburger Landschaft, this symposium was held at the medieval Stift Obernkirchen, Germany, from April 14th to 17th, 2011. Nearly one hundred Abstract Volume and Field Guide to Excursions palaeontologists, biologists, geologists and other scientists from sixteen countries participated. Annette Richter, Mike Reich (Eds.)

The tracks are preserved in the Helvetiafjellet For- mation (Barremian). A sedimentological characterization of the site indicates that the tracks formed on a beach/margin of a lake or interdistributary bay, and were preserved by flooding. In addition to the two imprints already known from the site, we describe at least 34 additional, pre- viously unrecognized pes and manus prints, including one trackway. Two pes morphotypes and one manus morphotype are recognized. Given the range of morphological variation and the pres- ence of manus tracks, we reinterpret all the prints as being from an ornithopod rather than a thero- pod, as previously described. We assign the smaller (morphotype A, pes; morphotype B, manus) to Caririchnium billsarjeanti. The larger (morphotype C, pes) track is assigned to Caririchnium sp., differing in size and interdigital angle from the two described ichnospecies C. burreyi and C. bill- sarjeanti.
