A morphometric characterization of cranial shape in terrestrial carnivorans based on fourier analysis
Pérez-Claros, Juan Antonio
; Martín-Serra, Alberto; Figueirido-Castillo, Francisco Borja; Janis, Christine Marie; Palmqvist-Barrena, Carlos Paul (2013-11-08)
A number of studies have shown that skull morphology reflects the ecological adaptations of terrestrial carnivores as well as their phylogenetic legacy. Here we use Fourier shape analysis for describing the dorsal outline ... -
An eye for a tooth: Thylacosmilus was not a marsupial ‘‘saber-tooth predator’’
Janis, Christine Marie; Figueirido-Castillo, Francisco Borja; DeSantis, Larisa; Lautenschlager, Stephan (PeerJ, 2020-06)
Background. Saber-toothed mammals, now all extinct, were cats or ‘‘cat-like’’ forms with enlarged, blade-like upper canines, proposed as specialists in taking large prey. During the last 66 Ma, the saber-tooth ecomorph has ... -
Dataset for 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 (Universidad de Málaga, 2019-06-10)
La base de datos hace referencia al artículo: Figueirido, B., Palmqvist, P., Pérez-Claros, J. A., & Janis, C. M. (2019). Sixty-six million years along the road of mammalian ecomorphological specialization. Proceedings of ... -
Ecomorphological determinations in the absence of living analogs: the predatory behavior of the marsupial lion (Thylacoleo carnifex) as revealed by elbow joint morphology.
Figueirido-Castillo, Francisco Borja; Martín-Serra, Alberto; Janis, Christine Marie (Cambridge University Press, 2016-05-06)
Thylacoleo carnifex, or the “pouched lion” (Mammalia: Marsupialia: Diprotodontia: Thylacoleonidae), was a carnivorous marsupial that inhabited Australia during the Pleistocene. Although today all researchers agree that ... -
Habitat changes and changing predatory habits in North American fossil canids.
Figueirido-Castillo, Francisco Borja; Martín-Serra, Alberto; Tseng, Zhijie Jack; Janis, Christine Marie (Springer Nature, 2015-08-18)
The spread of open grassy habitats and the evolution of long-legged herbivorous mammals with high-crowned cheek teeth have been viewed as an example of coevolution. Previous studies indicate that specialized predatory ... -
Kangaroo morphometrics: how Miocene kangaroos can inform us about palaeoenvironments and how giant Pleistocene kangaroos managed to locomote
(2015-05-27)Kangaroos are known today for their spectacular hopping locomotion, but kangaroo diversity in the past tells a different story. Some kinds of extinct kangaroos (sthenurines) grew so large that hopping would seem to be ... -
Postcranial elements of small mammals as indicators of locomotion and habitat.
Janis, Christine Marie; Martín-Serra, Alberto (Peer J, 2020)
Many studies have shown a correlation between postcranial anatomy and locomotor behavior in mammals, but the postcrania of small mammals (<5 kg) is often considered to be uninformative of their mode of locomotion due to ... -
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 ...
