Taxonomic identification of isolated theropod teeth: The case of the shed tooth crown associated with Aerosteon (Theropoda: Megaraptora) and the dentition of Abelisauridae
(Academic Press Ltd - Elsevier Science Ltd, 2020-04)
Shed teeth are usually the most abundant theropod material on a dinosaur fossil site and are constantly reported in the literature. Although new quantitative techniques have emerged to identify isolated theropod teeth with ...
The distribution of dental features in non-avian theropod dinosaurs: Taxonomic potential, degree of homoplasy, and major evolutionary trends
(Coquina Press, 2019-11)
Isolated theropod teeth are some of the most common fossils in the dinosaur fossil record and are continually reported in the literature. Recently developed quantitative methods have improved our ability to test the ...
The dentition of Manidens condorensis (Ornithischia; Heterodontosauridae) from the Jurassic Can˜ado´n Asfalto Formation of Patagonia: morphology, heterodonty and the use of statistical methods for identifying isolated teeth
(Taylor & Francis, 2013-05)
The recently described Manidens condorensis is one of the most completely known taxa of the family Heterodontosauridae from the southern landmasses. However, some dental aspects are not well known due to preservational ...
Isolated theropod teeth associated with a sauropod skeleton from the Late Cretaceous Allen Formation of Río Negro, Patagonia, Argentina
(Polish Academy of Sciences. Institute of Paleobiology, 2021-06)
The discovery of theropod shed teeth associated with sauropod remains is relatively common in Cretaceous deposits of Patagonia. However, only a handful of studies have thoroughly explored the phylogenetic affinities of the ...
Lactobacilli isolation from dental plaque and saliva of a group of patients with caries and characterization of their surface properties
(Elsevier, 2001-02)
The oral cavity is a complex ecosystem colonized by micro-organisms which play different roles. The aims of this study were to identify Lactobacillus strains from the teeth and saliva of children lacking in dental care and ...
Tooth replacement in Manidens condorensis: baseline study to address the replacement pattern in dentitions of early ornithischians
(The Palaeontological Association, 2021-05)
Dental replacement in Heterodontosauridae has been debated over the last five decades primarily on indirect evidence, such as the development of wear facets and the position of erupted teeth. Direct observation of unerupted ...
First occurrence of the giant shark carcharocles megalodon (Agassiz, 1843) (lamniformes; otodontidae) at Buenos Aires province, Argentina
(Milchwissenschaft - Milk Science International, 2021-08)
– Carcharocles megalodon is considered a macropredatory shark that inhabited the seas around the world from middle Miocene to late Pliocene. In Argentina, it has only been formally recorded at two localities. Here, we ...
Dentición de titanosaurios (Dinosauria, Sauropoda) del Cretácico Superior de la provincia de Río Negro, Argentina: morfología, inserción y reemplazoDentition of titanosaurs (Dinosauria, Sauropoda) from the Upper Cretaceous of Río Negro province, Argentina: morphology, implantation and replacement
(Asociacion Paleontologica Argentina, 2010-12)
Se describe la anatomía observada en un fragmento de dentario de titanosaurio saurópodo de la Formación Anacleto (Cretácico Superior de la provincia de Río Negro), compuesto por siete alvéolos. Dentro de los alvéolos se ...
Surface properties of lactobacilli isolated from healthy subjects
(Wiley Blackwell Publishing, Inc, 2008-06)
OBJECTIVE: Lactobacilli are considered cariogenic micro-organismS. As oral species of lactobacilli have not been thoroughly described, the aim of this work was to isolate and identify these organisms from teeth, tongue, ...
Modelización con Elementos Finitos de un Diente Referido al Género Giganotosaurus (Theropoda: Carcharodontosauridae)Finite element modelling of a tooth refrerred to the genus giganotosaurus coria and salgado, 1995 (Theropoda: Carcharodontosauridae)
(Asociación Paleontológica Argentina, 2004-12)
Se estudió cuantitativamente y por vez primera el diseño biomecánico del diente de un dinosaurio. Para ello se generó mediante tomografía computarizada una serie de imágenes transaxiales (separadas a intervalos de 1,5 mm) ...
