Stéphane Jouve, Conservateur-adjoint, Muséum de Marseille Invité ACKNOWLEDGMENTS First of all, I have to say that this work did not start with the Ph.D. program itself, this work started many years ago with the help of many people of different countries that, in one way or another, supported my dream of becoming a paleontologist. In this section I will express my gratitude in the language I can better explain my deep recognition to all of them. Dicho esto, quiero empezar agradeciendo a mis dos asesores, Pierre-Olivier Antoine y Armando Valdés Velásquez, por haber confiado en mi para realizar esta investigación. Yo les agradezco profundamente por su paciencia y apoyo durante estos tres años, por haberme motivado y conducido para dar este importante paso profesional en mi vida. Por consiguiente, agradezco profundamente a Pierre-Olivier Antoine, mi guía y aliado, el maestro y amigo que no vaciló nunca en hacer un esfuerzo adicional para que este proyecto se concrete. Gracias por todo el tiempo invertido, lo aprecio y respeto. Cada uno de sus consejos y enseñanzas durante estos tres años, y desde que nos conocimos, tanto haciendo trabajo de campo en la Amazonía de Iquitos como en el laboratorio, traslucieron su calidad humana y científica. He aprendido mucho sobre paleontología en todas nuestras conversaciones, por las cuales le estaré siempre agradecido. Además, estoy muy agradecido por el tiempo que pasé en Montpellier, por haberme hecho sentir como en casa, por proveerme de las mejores condiciones de trabajo y oportunidades para que esta investigación sea mejor cada día. Muchas gracias a Pierre-Olivier porque él y su familia –Maëva y Aloys –, fueron la mía en Montpellier. Yo le agradezco sinceramente a Armando Valdés Velásquez quien ha co-dirigido esta investigación desde Lima, Perú. A pesar de recién haberme conocido, Armando aceptó sin vacilar ser mi co-director. Le agradezco por las enseñanzas en cada conversación que tuvimos y la confianza que depositaste en mi, mostrando un compromiso desinteresado por llevar este proyecto adelante. Quiero agradecer a los revisores de la tesis, Torsten Scheyer y Diego Pol, por mostrar gran interés por mi trabajo y por haber aceptado evaluar esta investigación. Sus importantes carreras y obras científicas siempre me fueron inspiradoras. Asimismo, quiero expresar mi agradecimiento a los miembros del jurado, Emmanuel Douzery, Christian De Muizon, John Flynn y Stéphane Jouve. Agradezco a Stéphane por compartir sus conocimientos e ideas sobre cocodrilos fósiles conmigo en muchas conversaciones y misivas. Quiero hacer un reconocimiento especial a Christian de Muizon y a John Flynn. Desde que conocí a Christian hace muchos años en Lima cuando era director del Instituto Francés de Estudios Andinos (IFEA), nos apoyó a Mario Urbina y a mi, para desarrollar la paleontología de vertebrados en el Perú. De allí en adelante siempre fue incondicional y su ayuda se hizo sentir en momentos decisivos de mi carrera. Junto a Jean Vacher y Niels Valencia, Christian me incentivó para que estudiara ciencias biológicas con ayuda de una beca del IFEA otorgada durante la gestión de Jean Vacher, a quien agradezco y aprecio. Asimismo, las oportunidades que Christian me dio para trabajar por algunos meses en el Museum national d’Histoire naturelle (MNHN) sirvieron para que yo revisara y estudiara las vastas colecciones de cocodrilos y así, empezara la revisión de los caracteres de los cocodrilos fósiles y actuales registrados en la matriz filogenética que en esta tesis incluyo. Christian me enseñó las bases de la ciencia llamada paleontología, por lo que lo considero mi mentor. A John Flynn lo conocí en el 2004 durante la primera expedición en la que yo participé a los yacimientos paleontológicos de la zona de Iquitos. Desde ese año, en cada campaña a Iquitos, cada descubrimiento lo hemos vivido y trabajado juntos, palmo a palmo, y lo hemos celebrado juntos con Siete Raíces Sour. A John le agradezco por haberme apoyado en la decisión incluir los cocodrilos de Iquitos como parte importante de mi doctorado. Además le tengo que agradecer por haberme facilitado estadías y becas para trabajar en la colección de cocodrilos del American Museum of Natural History (AMNH). Incluso me brindó un espacio en el AMNH para enclaustrarme el último mes antes de entregar el manuscrito de mi tesis y poder terminarla a tiempo. También le agradezco por todos los intercambios epistolares en los que discutimos aspectos científicos de los artículos conformantes de esta tesis. Del AMNH, quiero agradecer a Ana Balcárcel por su extraordinario trabajo en el campo y en la preparación de fósiles en el laboratorio y a Carl Mehling por brindarme acceso a las colecciones de reptiles fósiles. Asimismo, expreso mi agradecimiento a Bruce MacFadden por haberme permitido ocupar por cuatro meses la Biblioteca Simpson del University of Florida Natural History Museum para escribir el segundo artículo de la tesis. Aprecio y agradezco mucho a Valerie DeLeon por haberme aceptado como alumno libre en la clase de morfometría geométrica en la University of Florida (UF); a Christopher Brochu, Paula Bona, Torsten Scheyer, Jorge Moreno-Bernal, Orángel Aguilera y Stéphane Jouve por facilitarme imágenes de cocodrilos fósiles; a Salvador Bailón del MNHN, Richard Hulbert y Kenneth Krysko de la UF, a Eberhard “Dino” Frey del Staatliches Museum für Naturkunde Karlsruhe, Karlsrhue, Germany (SMNK), y a R. Schoch del Staatliches Museum für Naturkunde Stuttgart, Stuttgart (SMNS) por amablemente brindarme acceso a las colecciones de cocodrilos fósiles y actuales a su cargo. Quisiera expresar mi agradecimiento y respeto a todos y cada uno de los miembros del Institute des Sciences de l’Evolution (ISEM). En el ISEM hice muchos y grandes amigos, entre ellos mi compañero de ofici na Abdou Mahboubi y el “big chief” Laurent Marivaux. Agradezco a Maëva Orliac por su constante ayuda en análisis de filogenia, conversaciones sobre arte científico y por acogerme en su oficina los meses antes de la sustentación. Agradezco a Julien Claude y Renaud Lebrun por sus valiosas enseñanzas sobre morfometría geométrica. Aprecio mucho la ayuda que me brindó Anusha Ramdarshan para evaluar el mircrodesgaste en dientes de caimanes “moledores”. Agradezco profundamente a la Escuela Doctoral Franco-Peruana de Ciencias de la Vida (EDFPCV) por otorgarme una beca por tres años, sin la cual no habría sido posible hacer esta investigación; a José Espinoza, director de la EDFPCV y a Rebeca Caldas de contabilidad por su constante preocupación y ayuda. Asimismo, a las personas e instituciones, peruanas y francesas que conforman la EDFPCV y que siempre estuvieron dispuestas a resolver cualquier situación adversa durante estos tres años: a Fabiola León- Velarde, rectora de la Universidad Peruana Cayetano Heredia; a Gisella Orjeda, presidenta del Concejo Nacional de Ciencia, Tecnología e Innovación Tecnológica; a Philippe Benassi agregado de Cooperación Universitaria de la Embajada de Francia en Lima y a su asistente Eliana Noriega; y particularmente a Jean-Loup Guyot, director en Lima del Institut de recherche pour le developpement (IRD), quien me ha brindado su consejo y amistad en todo momento requerido. Tengo que ofrecer un profundo agradecimiento a todos los que participaron en las expediciones a Iquitos y Fitzcarrald y que hicieron posible que los magníficos fósiles de cocodrilos tema de esta tesis

It is one of the largest of crocodilians, with males attaining lengths of up to 5 m. The current distribution of Tomistoma extends over lowland regions of eastern Sumatra, Kalimantan and western Java (Indonesia) and Sarawak and Peninsular Malaysia (Malaysia), within 5 degrees north and south of the equator (Stuebing et al. 2006). Tomistoma apparently occurred in southern Thailand historically, but there have been no reports since at least the 1970s and it is probably extirpated there (Ratanakorn et al.

Tentative remains from Europe, Morocco, and Madagascar may extend their range into the Middle Jurassic. Here we report the first unambiguous Middle Jurassic (late Bajocian–Bathonian) atoposaurid: an anterior dentary from the Isle of Skye, Scotland, UK. A comprehensive review of atoposaurid specimens demonstrates that this dentary can be referred to Theriosuchus based on several derived characters, and differs from the five previously recog- nized species within this genus. Despite several diagnostic features, we conservatively refer it to Theriosuchus sp., pending the discovery of more complete material. As the oldest known definitively diagnostic atoposaurid, this discovery indicates that the oldest members of this group were small-bodied, had heterodont dentition, and were most likely widespread components of European faunas.

    8. Archosaur Phylogeny and the Relationships of the Crocodylia

    8. Archosaur phylogeny and the relationships of the Crocodylia MICHAEL J. BENTON Department of Geology, The Queen's University of Belfast, Belfast, UK JAMES M. CLARK* Department of Anatomy, University of Chicago, Chicago, Illinois, USA Abstract The Archosauria include the living crocodilians and birds, as well as the fossil dinosaurs, pterosaurs, and basal 'thecodontians'. Cladograms of the basal archosaurs and of the crocodylomorphs are given in this paper. There are three primitive archosaur groups, the Proterosuchidae, the Erythrosuchidae, and the Proterochampsidae, which fall outside the crown-group (crocodilian line plus bird line), and these have been defined as plesions to a restricted Archosauria by Gauthier. The Early Triassic Euparkeria may also fall outside this crown-group, or it may lie on the bird line. The crown-group of archosaurs divides into the Ornithosuchia (the 'bird line': Orn- ithosuchidae, Lagosuchidae, Pterosauria, Dinosauria) and the Croco- dylotarsi nov. (the 'crocodilian line': Phytosauridae, Crocodylo- morpha, Stagonolepididae, Rauisuchidae, and Poposauridae). The latter three families may form a clade (Pseudosuchia s.str.), or the Poposauridae may pair off with Crocodylomorpha. The Crocodylomorpha includes all crocodilians, as well as crocodi- lian-like Triassic and Jurassic terrestrial forms. The Crocodyliformes include the traditional 'Protosuchia', 'Mesosuchia', and Eusuchia, and they are defined by a large number of synapomorphies, particularly of the braincase and occipital regions.

    First Remains of Diplocynodon Cf. Ratelii from the Early Miocene Sites of Ahníkov (Most Basin, Czech Republic)

    First remains of Diplocynodon cf. ratelii from the early Miocene sites of Ahníkov (Most Basin, Czech Republic) Milan Chroust, Martin MazuCh, Martin ivanov, Boris Ekrt & ÀngEl h. luján Fossil crocodylians from the early Miocene (Eggenburgian, MN3a) sites of Ahníkov (Most Basin, Czech Republic) are described in this paper. The new material presented here includes over 200 remains (bones, teeth and osteoderms), and therefore constitutes the largest crocodylian sample known from the fossil record of the Czech Republic. Assignment of the specimens to the fossil alligatoroid taxon Diplocynodon cf. ratelii Pomel, 1847 (family Diplocynodontidae) is justified by the presence of several cranial and postcranial features. In the Czech Republic, this species has been previously reported only from the Tušimice site (MN3, Most Basin, Ohře/Eger Graben). The majority of the material reported from Ahníkov is composed of disarticulated juvenile individuals. Both sites are most likely attributable to the specific environment of swampy areas, where crocodile hatchlings would hide from predators. The presence of the genus Diplocynodon supports the assumption of rather warm climatic conditions in Central Europe during the early to middle Miocene, as well as a swampy depositional environment previously inferred for Ahníkov. However, some squamate taxa suggest the existence of additional, surrounding palaeoenvironment characterised by a more open landscape with slightly drier conditions. • Key words: fossil crocodiles, alligatoroid, Ahníkov, Ohře/Eger Graben, Eggenburgian.

    Crocodiles Alter Skin Color in Response to Environmental Color Conditions

    www.nature.com/scientificreports OPEN Crocodiles Alter Skin Color in Response to Environmental Color Conditions Received: 3 January 2018 Mark Merchant1, Amber Hale2, Jen Brueggen3, Curt Harbsmeier4 & Colette Adams5 Accepted: 6 April 2018 Many species alter skin color to varying degrees and by diferent mechanisms. Here, we show that Published: xx xx xxxx some crocodylians modify skin coloration in response to changing light and environmental conditions. Within the Family, Crocodylidae, all members of the genus Crocodylus lightened substantially when transitioned from dark enclosure to white enclosures, whereas Mecistops and Osteolaemus showed little/no change. The two members of the Family Gavialidae showed an opposite response, lightening under darker conditions, while all member of the Family Alligatoridae showed no changes. Observed color changes were rapid and reversible, occurring within 60–90 minutes. The response is visually- mediated and modulated by serum α-melanocyte-stimulating hormone (α-MSH), resulting in redistribution of melanosomes within melanophores. Injection of crocodiles with α-MSH caused the skin to lighten. These results represent a novel description of color change in crocodylians, and have important phylogenetic implications. The data support the inclusion of the Malayan gharial in the Family Gavialidae, and the shift of the African slender-snouted crocodile from the genus Crocodylus to the monophyletic genus Mecistops. Te rapid alteration of skin color is well known among a wide assortment of ectothermic vertebrates and inver- tebrates1. Adaptive skin color changes may occur for a variety of reasons, including communication, thermal regulation, and crypsis1. Te modifcation of skin pigmentation is achieved by either physiological or morpho- logical mechanisms1.

Even when multiple studies exploring the potential variety within a 16taphonomic process exist, quantitative methods for comparing these datasets in order to identify 17larger scale patterns have been understudied. This research uses modern bite marks collected 18from 21 of the 23 generally recognized species of extant Crocodylia to explore statistical and 19phylogenetic methods of synthesizing taphonomic datasets. Bite marks were identified, and 20specimens were then coded for presence or absence of different mark morphotypes. Attempts to 21find statistical correlation between trace types, marking animal vital statistics, and sample 22collection protocol were unsuccessful. Mapping bite mark character states on a eusuchian 23phylogeny successfully predicted the presence of known diagnostic, bisected marks in extinct 24taxa. Predictions for clades that may have created multiple subscores, striated marks, and 25extensive crushing were also generated. Inclusion of fossil bite marks which have been positively 26associated with extinct species allow this method to be projected beyond the crown group.
