A área estudada abrange parte dos municípios de Sousa, São João do Rio do Peixe, Marizópolis, Aparecida, Triunfo e Santa Helena no oeste da Paraíba. Em termos geológicos está inserida na Bacia Sedimentar do Rio do Peixe e em rochas do embasamento cristalino. A origem da Bacia do Rio do Peixe está relacionada à abertura do Oceano Atlântico, quando ocorreram falhamentos transcorrentes ao longo de lineamentos pretéritos do embasamento. Inclui essencialmente rochas cretáceas do Grupo Rio do Peixe, constituído pelas formações Antenor Navarro, Sousa e Rio Piranhas. Essa área é conhecida mundialmente por suas ocorrências de pegadas fósseis e atualmente conta com um sítio aberto à visitação, o Monumento Natural Vale dos Dinossauros. A região de Sousa atende aos critérios básicos estabelecidos pelos Geoparques Globais da UNESCO para a criação de um geoparque, ou seja: representa uma área suficientemente grande e de limites bem definidos para servir ao desenvolvimento sustentável local, notadamente através do turismo; envolve um número de sítios geológicos e paleontológicos de importância científica (inclusive de relevância internacional) que devem ser preservados; bem como inclui aspectos arqueológicos, ecológicos, históricos e culturais. No inventário dos geossítios, foram avaliadas e cadastradas 20 localidades, sendo 12 com ocorrências de pegadas fósseis e oito representando a geologia da Bacia do Rio do Peixe e seu contato com o embasamento. Seguindo os critérios de classificação do aplicativo GEOSSIT, base de dados do Serviço Geológico do Brasil – CPRM, uma geossítio apresentou relevância internacional, 15 geossítios e sítios da geodiversidade foram classificados como de relevância nacional e quatro sítios da geodiversidade foram considerados como de importância regional. As ocorrências icnofossilíferas levantadas incluem dinossauros Theropoda (Eubrontes isp., cf. Anchisauripus isp., Moraesichinium barberenae e outros indeterminados), Ornithopoda (Caririchnium magnificum, Sousaichnium pricei e Staurichnium diogenis), Sauropoda e Ankylosauria, crocodilianos Mesoeucrocodylia, pegadas de natação, raras pegadas lacertóides, uma possível pista de mamífero e icnofósseis de invertebrados. Alguns sítios apresentam conjuntos produzidos por manadas de Sauropoda, incluindo impressões de mãos e pés. As feições geológicas e principalmente os icnofósseis encontrados na Bacia do Rio do Peixe, junto aos demais atributos levantados na área estudada, justificam a criação de um geoparque nos moldes preconizados por um Geoparque Global da UNESCO (UNESCO GLOBAL GEOPARK). PALAVRAS CHAVE: PATRIMÔNIO GEOLÓGICO; GEOPARQUE; RIO DO PEIXE. 1 ABSTRACT The present work deals with a technical and diagnostic study, carried out by the Geological Service of Brazil, to support the proposal for the creation of the Rio do Peixe Geopark, within the Geoparks Project, recognizing its importance for geotourism, geoconservation, educational purposes and scientific research. The studied area includes part of the municipalities of Sousa, São João do Rio do Peixe, Marizópolis, Aparecida, Triunfo e Santa Helena in the west of Paraíba. In geological terms it is inserted in the Rio do Peixe Sedimentary Basin and in crystalline basement rocks. The origin of the Rio do Peixe Basin is related to the opening of the Atlantic Ocean, when there were transcurrent faults along previous basements of the basement. It includes essentially Cretaceous rocks of the Rio do Peixe Group, constituted by the Antenor Navarro, Sousa and Rio Piranhas formations. This area is known worldwide for its occurrences of fossil footprints and currently has a site open to visitation, the Natural Monument Valley of the Dinosaurs. The Sousa region fulfills the basic criteria established by the UNESCO Global Geoparks for the creation of a geopark, such as: it represents a sufficiently large area and well defined limits to serve the local sustainable development, notably through tourism; involves a number of geological and paleontological sites of scientific value (also of international relevance) and sites of potential educacional e geotouristic use, which must be preserved; as well as archaeological, ecological, historical and cultural aspects. In the inventory of geosites, 20 localities were evaluated and registered, 12 with fossil footprint occurrences and 8 representing the geology of the Rio do Peixe Basin and its contact with the basement. Following the classification criteria of the GEOSSIT, database of the Geological Survey of Brazil - CPRM, 1 locality presented international relevance, 15 were classified as national relevance and 4 of them were considered of regional importance. The icnofossiliferous occurrences include Theropoda dinosaurs (Eubrontes isp., cf. Anchisauripus isp., Moraesichinium barberenae and others), Ornithopoda (Caririchnium magnificum, Sousaichnium pricei and Staurichnium diogenis), Sauropoda and Ankylosauria, crocodilians Mesoeucrocodylia, swimming footprints, rare lacertoid footprints, a possible mammalian track and invertebrate icnofossils. Some sites feature sets produced by Sauropoda herds, including manus and pes prints. The geological features and especially the icnofossils found in the Rio do Peixe Basin, along with the other attributes raised in the studied area, justify the creation of a geopark in the form recommended by a UNESCO GLOBAL GEOPARK.

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.

  • A Review of Large Cretaceous Ornithopod Tracks, with Special Reference to Their Ichnotaxonomy

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.

  • Los Hadrosaurios (Ornithopoda, Hadrosauroidea)
    ARTÍCULO CIENTÍFICO Ramírez-Velasco- Hadrosaurios de México - 105-147 LOS HADROSAURIOS (ORNITHOPODA, HADROSAUROIDEA) MEXICANOS: UNA REVISIÓN CRÍTICA THE MEXICAN HADROSAURS (ORNITHOPODA, HADROSAUROIDEA): A CRITICAL REVIEW Ángel Alejandro Ramírez Velasco1* 1Posgrado en Ciencias Biológicas, Instituto de Geología, Universidad Nacional Autónoma de México, Circuito de la investigación s/n, Ciudad Universitaria, Coyoacán, Ciudad de México, 04510. *Correspondence: [email protected] Received: 2021-02-05. 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.)
