Biomechanical simulations reveal a trade-off between adaptation to glacial climate and dietary niche versatility in European cave bears.
Pérez-Ramos, Alejandro; Tseng, Jack; Grandal D'Anglade, Aurora; Rabeder, Gernot; Pastor, Francisco; Figueirido-Castillo, Francisco Borja[et al.] (AAAS, 2020-04-01)The cave bear is one of the best known extinct large mammals that inhabited Europe during the “Ice Age,” becoming extinct ≈24,000 years ago along with other members of the Pleistocene megafauna. Long-standing hypotheses ... -
Carrying capacity, available meat and the fossil record of the Orce sites (Baza Basin, Spain)
Rodríguez-Gómez, Guillermo; Espigares-Ortiz, María Patrocinio; Martínez-Navarro, Bienvenido; Ros-Montoya, Sergio; Guerra-Merchán, Antonio; Martín-González, Jesús A.; Campaña, Isidoro; Pérez-Ramos, Alejandro; Granados, Alejandro; García-Aguilar, José Manuel; Rodríguez-Ruiz, María Dolores; Palmqvist-Barrena, Carlos Paul[et al.] (MDPI, 2024)The Early Pleistocene sites of Orce in southeastern Spain, including Fuente Nueva-3, Barranco León and Venta Micena, provide important insights into the earliest hominin populations and Late Villafranchian large mammal ... -
Distinct Predatory Behaviors in Scimitar- and Dirk-Toothed Sabertooth Cats.
Figueirido-Castillo, Francisco Borja; Lautenschlager, Stephan; Pérez-Ramos, Alejandro; Van Valkenburgh, Blaire (Cell Press, 2018-10-22)Over the Cenozoic, large cat-like forms have convergently evolved into specialized killers of “megaherbivores” that relied on their large, and laterally compressed (saber-like) canines to rapidly subdue their prey. Scimitar- ... -
Investigating the land‑to‑sea transition in carnivorans from the evolution of sacrum morphology in pinnipeds
Esteban Núñez, Juan Miguel; Martín-Serra, Alberto; Pérez-Ramos, Alejandro; Rybczynski, Natalia; Pastor, Francisco J.; Figueirido-Castillo, Francisco Borja[et al.] (Springer, 2023)The form and function of the sacrum are of great relevance to understand the evolution of locomotion in tetrapods because it is a key piece of the vertebrate skeleton. The sacrum connects the caudal and presacral regions ... -
Phenotypic integration in the carnivoran backbone and the evolution of functional differentiation in metameric structures
Martín-Serra, Alberto; Pérez-Ramos, Alejandro; Pastor, Francisco; Velasco, David; Figueirido-Castillo, Francisco Borja (2021)Explaining the origin and evolution of a vertebral column with anatomically distinct regions that characterizes the tetrapod bodyplan provides understanding of how metameric structures become repeated and how they acquire ... -
Serial disparity in the carnivoran backbone unveil a complex adaptive role in metameric evolution.
Figueirido-Castillo, Francisco Borja; Martín-Serra, Alberto; Pérez-Ramos, Alejandro; Velasco, David; Pastor, Francisco J.; Benson, Roger J.[et al.] (2021)Organisms comprise multiple interacting parts, but few quantitative studies have analysed multi-element systems, limiting understanding of phenotypic evolution. We investigate how disparity of vertebral morphology varies ... -
Sharing food with hyenas: a latrine of Pachycrocuta brevirostris in the Early Pleistocene assemblage of Fuente Nueva‑3 (Orce, Baza Basin, SE Spain)
Espigares-Ortiz, María Patrocinio; Palmqvist-Barrena, Carlos Paul; Rodríguez-Ruiz, María Dolores; Martínez-Navarro, Bienvenido; Ros-Montoya, Sergio; Pérez-Ramos, Alejandro; Rodríguez-Gómez, Guillermo; Guerra-Merchán, Antonio; García-Aguilar, José Manuel; Granados, Alejandro; Campaña, Isidoro; Martínez-Navarro, Bienvenido[et al.] (Springer, 2023)The Early Pleistocene archeological site of Fuente Nueva-3 (FN3) preserves some of the oldest evidence of hominin presence in Western Europe, including a huge assemblage of Oldowan tools and evidence of butchering and ... -
The late Early Pleistocene site of Fuente Nueva-3 (Guadix-Baza Depression, SE Spain): a hyena latrine developed on a quicksand trap for megaherbivores?
Palmqvist-Barrena, Carlos Paul; Campaña, Isidoro; Granados, Alejandro; Martínez-Navarro, Bienvenido; Pérez-Ramos, Alejandro; Rodríguez-Gómez, Guillermo; Guerra-Merchán, Antonio; Ros-Montoya, Sergio; Rodríguez-Ruiz, María Dolores; García-Aguilar, José Manuel; Hernández-Jolín, Víctor; Espigares-Ortiz, María Patrocinio[et al.] (Springer, 2024)The late Early Pleistocene archaeological site of Fuente Nueva-3 (FN3), which lies in the Guadix-Baza Depression (SE Spain) and is dated to ~ 1.4 Ma, contributes some of the oldest evidence of hominin presence in Western ...
