Déjà vu: a reappraisal of the taphonomy of quarry VM4 of the Early Pleistocene site of Venta Micena (Baza Basin, SE Spain)
Palmqvist-Barrena, Carlos Paul
; Espigares-Ortiz, María Patrocinio; Pérez-Claros, Juan Antonio; Figueirido-Castillo, Francisco Borja; Guerra-Merchán, Antonio; Ros-Montoya, Sergio; Rodríguez-Gómez, Guillermo; García-Aguilar, José Manuel; Granados, Alejandro; Martínez-Navarro, Bienvenido[et al.] (Nature Research, 2022)
Venta Micena, an Early Pleistocene site of the Baza Basin (SE Spain), preserves a rich and diverse assemblage of large mammals. VM3, the main excavation quarry of the site, has been interpreted as a den of the giant hyaena ... -
Déjà vu: on the use of meat resources by sabretooth cats, hominins, and hyaenas in the Early Pleistocene site of Fuente Nueva 3 (Guadix‑Baza Depression, SE Spain)
Palmqvist-Barrena, Carlos Paul; Rodríguez-Gómez, Guillermo; Martínez-Navarro, Bienvenido; Espigares-Ortiz, María Patrocinio; Figueirido-Castillo, Francisco Borja; Ros-Montoya, Sergio; Guerra-Merchán, Antonio; Granados, Alejandro; García-Aguilar, José Manuel; Pérez-Claros, Juan Antonio[et al.] (Springer, 2022)
The late Early Pleistocene archaeological site of Fuente Nueva 3 (Orce, Guadix-Baza Depression, SE Spain), dated to ~1.4 Ma, provides evidence on the subsistence strategies of the first hominin population that dispersed ... -
Demythologizing Arctodus simus, the ‘short-faced’ long-legged and predaceous bear that never was
Figueirido-Castillo, Francisco Borja; Pérez-Claros, Juan Antonio; Torregrosa, Vanessa; Martín-Serra, Alberto; Palmqvist-Barrena, Carlos Paul (Taylor and Francis, 2010)
In this study, we review the previous evidence on the paleobiology of the giant, ‘short-faced’ bear Arctodus simus (Mammalia: Carnivora: Ursidae) and contribute new ecomorphological inferences on the paleobiology of this ... -
Generic diversity and septal complexity in Cretaceous ammonoids. Effects of oceanic anoxic events on the ammonoid evolutionary dynamic
Pérez-Claros, Juan Antonio (2024-09-08)
En este trabajo se analiza la relación entre el número de géneros de ammonoideos planiespirales del Cretácico y su complejidad sutural estimada mediante su dimensión fractal. Se confirma que la dinámica de la diversidad ... -
Patterns of morphological integration in the appendicular skeleton of mammalian carnivores.
Martín-Serra, Alberto; Figueirido-Castillo, Francisco Borja; Pérez-Claros, Juan Antonio; Palmquist-Gomes, Paul (Oxford Academic, 2015-02-01)
We investigated patterns of evolutionary integration in the appendicular skeleton of mammalian carnivores. The findings are discussed in relation to performance selection in terms of organismal function as a potential ... -
Sixty-six million years along the road of mammalian ecomorphological specialization.
Figueirido-Castillo, Francisco Borja; Palmqvist-Barrena, Carlos Paul; Pérez-Claros, Juan Antonio; Janis, Christine Marie (Proceedings of the National Academy of Sciences of the United States, 2019-06-25)
The fossil record of the large terrestrial mammals of the NorthAmerican Cenozoic has previously been quantitatively summarizedin six sequential episodes of faunal associations—“evolutionary faunas”—that correspond well ... -
Sutural complexity and body size in Cretaceous ammonoids: Macroevolutionary decoupling of correlated features
Pérez-Claros, Juan Antonio (Elsevier, 2022-04)
The relationship between sutural complexity (estimated as fractal dimension) and body size is analysed for a sample of 204 genera of Cretaceous ammonoids. Although both characteristics are significantly correlated with ... -
The giant hyena Pachycrocuta brevirostris: modelling the bone-cracking behavior of an extinct carnivore
Palmqvist-Barrena, Carlos Paul; Martínez-Navarro, Bienvenido; Pérez-Claros, Juan Antonio; Torregrosa, Vanessa; Figueirido-Castillo, Francisco Borja; Jiménez-Arenas, Juan Manuel; Espigares-Ortiz, María Patrocinio; Ros-Montoya, Sergio; De Renzi, Miquel[et al.] (ELSEVIER, 2011)
The giant hyena Pachycrocuta brevirostris was the largest bone-cracking carnivore that ever existed. With the mass of a lioness, it had massive limbs with shortened distal bones and a heavy, powerfully built mandible with ...
