Ryan1,2, and Thomas M. Cullen3 1Dept. Earth Sciences, Carleton University, Ottawa, Ontario, K1S 5B6, Canada; [email protected] 2Cleveland Museum of Natural History, 1 Wade Oval Drive, Cleveland, Ohio 41106-1767, USA; [email protected] 3Field Museum of Natural History, 1400 S Lake Shore Drive, Chicago, Illinois 60605, USA; thomas.cullen@ fieldmuseum.org Abstract: Positional variation is documented in ornithomimid pedal unguals from the Dinosaur Park and Horseshoe Canyon Formations of Alberta, Canada, and characters for identifying the position of isolated ornithomimid pedal unguals are discussed. Ungual morphology has been used recently to argue for the coexistence of two distinct ornithomimosaurs, a basal taxon and distinctly more derived taxon, in the Early Cretaceous Arundel Clay of Maryland, USA. However, these conclusions are based on misconceptions of the morphology and positional variability of ornithomimosaur unguals. Some characters previously cited as diagnostic of ornithomimosaur unguals are not actually observed in this clade, or are more homoplastically distributed among theropods. Other characters proposed to distinguish between the two pedal ungual morphs in the Arundel Clay material are shown in the Albertan ornithomimid material to consistently distinguish the dif- ferent ungual positions within the pes of one individual. Claims of multiple distinct ornithomimosaur taxa in the Arundel Clay are premature, as the two pedal ungual morphotypes more likely represent positional variation in a single taxon. INTRODUCTION itional variation in a complete set of unguals from a single pes of the ornithomimid Aepyornithomimus tugrikinensis The ornithomimosaur pes is regarded as an important was described and figured.

Vertebrate Anatomy Morphology Palaeontology 6:68-72 68 ISSN 2292-1389 Rebuttal of McFeeters, Ryan and Cullen, 2018, ‘Positional variation in pedal unguals of North American ornithomimids (Dinosauria, Theropoda): A Response to Brownstein (2017)’ Chase Doran Brownstein Stamford Museum, 39 Scofieldtown Road, Stamford, CT 06903, USA; [email protected] Abstract: The Arundel Clay of Maryland is among the only Early Cretaceous terrestrial units known from eastern North America. Research on some theropod dinosaur bones from this layer has indicated the presence of two ornithomimosaur taxa in the assemblage. However, a recent paper discussed issues with the definite assignment of any of these unguals to Ornithomimosauria and suggested that morphological differences originally interpreted to be indicative of the presence of two ornithomimosaurs could be explained by positional variation. Here, I show that substantial evidence persists for the presence of two ornithomimosaurs in the Arundel Clay assemblage, even considering the recent description of positional variation in ornithomimosaur pedal unguals. Furthermore, the argument against the confident assignment of these unguals to ornithomimosaurs is shown to be based on oversimplified comparisons that do not take into account the combination of features in the Arundel specimens that allow for their assignment to that clade. Although several small points made in the initial paper describing the Arundel specimens are incorrect or unsubstantiated, the differences between the Maryland unguals are outside the spectrum of positional variation and are indicative of the presence of two ornithomimosaurs in the Arundel Clay assemblage. The Arundel Clay of Maryland is an Aptian unit (e.g., Lipka major acts in that paper: (1) the confident assignment of the et al.

FC 2016 August Newsletter.Pub
FOSSIL CLUB OF LEE COUNTY AUGUST 2016 Letter from the President Last month we had a small problem with the newsletter, so I hope this one gets to you this month! I believe that eventually all current members got theirs last month, but it was a bit difficult to get it forwarded, and if you missed it, I apologize! Remember, you can always access the newsletters from the club website: www.fcolc.com Last month one of our long time members, Gunther Lobisch, gave a terrific fossil presentation. He spoke about his personal experiences and stories about fossil collecting. Gunther also brought a large assortment of quality fossils to show and tell and members were encouraged to view them up close. This is the type of activities that help us all learn. Seeing the actual fossil in person is the very best way to learn identification. That is one reason we always encourage show and tell at each meeting. Please do not be shy, but bring in your fossils so others can see them. The October 15 fossil hunt at Mosaic is close to being filled up. We are awarded one trip a year, at their discretion, and ask that members who want to go to please attend the meetings so as to be able to sign up to go. We are allowed only 30 spots, so if you cannot make the monthly meetings to sign up you probably won't be able to go. Sorry, but the trip is very limited. Al Govin will have the signup sheet at the meeting.

En La Nomenclatura De Taxones Paleontológicos Y Zoológicos
Bol. R. Soc. Esp. Hist. Nat., 114, 2020: 177-209 Desenfado (e incluso humor) en la nomenclatura de taxones paleontológicos y zoológicos Casualness (and even humor) in the nomenclature of paleontological and zoological taxa Juan Carlos Gutiérrez-Marco Instituto de Geociencias (CSIC, UCM) y Área de Paleontología GEODESPAL, Facultad CC. Geológicas, José Antonio Novais 12, 28040 Madrid. [email protected] Recibido: 25 de mayo de 2020. Aceptado: 7 de agosto de 2020. Publicado electrónicamente: 9 de agosto de 2020. PALABRAS CLAVE: Nombres científicos, Nomenclatura binominal, CINZ, Taxonomía, Paleontología, Zoología. KEY WORDS: Scientific names, Binominal nomenclature, ICZN, Taxonomy, Paleontology, Zoology. RESUMEN Se presenta una recopilación de más de un millar de taxones de nivel género o especie, de los que 486 corresponden a fósiles y 595 a organismos actuales, que fueron nombrados a partir de personajes reales o imaginarios, objetos, compañías comerciales, juegos de palabras, divertimentos sonoros o expresiones con doble significado. Entre las personas distinguidas por estos taxones destacan notablemente los artistas (músicos, actores, escritores, pintores) y, en menor medida, políticos, grandes científicos o divulgadores, así como diversos activistas. De entre los personajes u obras de ficción resaltan los derivados de ciertas obras literarias, películas o series de televisión, además de variadas mitologías propias de las diversas culturas. Los taxones que conllevan una terminología erótica o sexual más o menos explícita, también ocupan un lugar destacado en estas listas. Obviamente, el conjunto de estas excentricidades nomenclaturales, muchas de las cuales bordean el buen gusto y puntualmente rebasan las recomendaciones éticas de los códigos internacionales de nomenclatura, representan una ínfima minoría entre los casi dos millones de especies descritas hasta ahora.

Completeness of the Dinosaur Fossil Record: Disentangling Geological and Anthropogenic Biases
COMPLETENESS OF THE DINOSAUR FOSSIL RECORD: DISENTANGLING GEOLOGICAL AND ANTHROPOGENIC BIASES by DANIEL DAVID CASHMORE A thesis submitted to the University of Birmingham for the degree of DOCTOR OF PHILOSOPHY September 2019 School of Geography, Earth and Environmental Sciences, College of Life and Environmental Sciences, University of Birmingham University of Birmingham Research Archive e-theses repository This unpublished thesis/dissertation is copyright of the author and/or third parties.

Abstract Non-avian dinosaurs were a highly successful clade of terrestrial tetrapods that dominated Mesozoic ecosystems. Their public and scientific popularity makes them one of most intensely researched and understood fossil groups. Key to our understanding of their evolutionary history are interpretations of their changing diversity through geological time. However, spatiotemporal changes in fossil specimen completeness, diagnostic quality, and sampling availabil- ity can bias our understanding of a group’s fossil record. Methods quantifying the level of skeletal and phylogenetic information available for a fossil group have previously been used to assess potential bias. In this thesis, these meth- ods are used to critically assess the saurischian dinosaur fossil record, includ- ing an examination of changes in specimen completeness through research time.
