ABSTRACT The great North American Pleistocene pantherine felid Panthera atrox has had a turbulent phylogenetic history, and has been claimed to show affinities to both the jaguar and the tiger; currently, it is most often regarded as a subspecies of the extant lion. The cranial, mandibular, and dental morphology of Panthera atrox was compared with those of extant lions, jaguars, and tigers using bivariate, multivariate, and shape analyses. Results indicate that the skull of Panthera atrox… 
Phylogenetics of Panthera, including Panthera atrox, based on craniodental characters
The phylogenetic position of Panthera atrox within Felidae is still controversial despite many morphological and molecular studies addressing its relationships. This is in part due to the lack of
Oldest Known Pantherine Skull and Evolution of the Tiger
TLDR
This find supports a north-central Chinese origin of the tiger lineage, and demonstrates that various parts of the cranium, mandible, and dentition evolved at different rates.
The fossil American lion (Panthera atrox) in South America: Palaeobiogeographical implications
Abstract By the late 19th and early 20th centuries, authors described several specimens belonging to a very large felid, the size of a lion, from some Late Pleistocene localities at southern Chile
Endocranial Morphology of the Extinct North American Lion (Panthera atrox)
TLDR
CT scans of a skull of P. atrox from the Pleistocene La Brea Tar pits were used to generate the first virtual endocranium for this species and to elucidate previously unknown details of its brain size and gross structure, cranial nerves, and inner-ear morphology.
First Asian record of Panthera (Leo) fossilis (Mammalia, Carnivora, Felidae) in the Early Pleistocene of Western Siberia, Russia.
TLDR
A lion-like pantherine felid is described as Panthera (Leo) fossilis from the late Early Pleistocene sediments of the Kuznetsk Basin (Western Siberia, Russia), which considerably extends the current notion of the eastward expansion of the most ancient lions.
First occurrence of Panthera atrox (Felidae, Pantherinae) in the Mexican state of Hidalgo and a review of therecord of felids from the Pleistocene of Mexico
Abstract. Panthera atrox was a common large-sized cat in North America during the late Pleistocene. An isolated lower canine and a fifth metacarpal bone referable to this species were recovered from
Geographical variation and phylogenetics of modern lions based on craniometric data
TLDR
The results of multivariate analysis of craniometric data indicate that lion skulls vary considerably throughout their geographical range and that the variation is greater within populations than between them, a significant subdivision being found only between sub-Sahara Africa and North Africa/Asia.
Functional limb morphology of extinct carnivores Smilodon fatalis, Panthera atrox, and Canis dirus based on comparisons with four extant felids and one extant canid
TLDR
In the geometric morphometric analysis of the forelimb, the cursorial carnivores differed from non-cursorial felids in glenoid fossa shape, humeral greater and lesser tubercles and radial tuberosity positioning, and distal radioulnar joint articular facet shape.
The clavicles of Smilodon fatalis and Panthera atrox (mammalia: Felidae) from Rancho La Brea, Los Angeles, California
TLDR
This study includes a reevaluation of clavicles that have been previously assigned to S. fatalis, which are more likely to be those of Panthera atrox, and the description of pantherine catClavicles, and reports distinctive morphology of the clavicle morph of Acinonyx jubatus.
Landmark Analysis of Musteloid Carnassials Applied to Taxonomic Identification and Examination of Sexual Dimorphism and Regional Morphotypes

TLDR
This study presents the results of a cladistic study encompassing 45 osteological and dental characters in the skull and mandible, as well as 13 soft‐tissue and behavioural characters, which show the clouded leopard is the most basal pantherine, followed by the snow leopard.
Systematic position of the cave lion Panthera spelaea (Goldfuss) based on cranial and dental characters
TLDR
The cranial morphology of P. spelaea confirms its phylogenetic position within the lion group, whereas many of the characters supporting the cave lion's relationship with the tiger are primitive.

Molecular phylogeny of the extinct cave lion Panthera leo spelaea.
TLDR
Phylogenetic analysis shows that the ancient sequences form a clade that is most closely related to the extant lions from Africa and Asia; at the same time, cave lions appear to be highly distinct from their living relatives.
Taphonomy and palaeoecology of Olduvai Bed-I (Pleistocence, Tanzania).
TLDR
The interpretation of the palaeoenvironments is that the middle Bed-I faunas indicate a very rich closed woodland environment, richer than any part of the present-day savanna biome in Africa, changing to less rich woodland in upperBed-I with a trend towards more open and seasonal woodlands at the top of the series.
