“…Various workers (Gazin, 1934; Zakrzewski, 1967; Bjork, 1970; Ray et al ., 1981; Anderson, 1989; Martin, 1989) examined the possible phylogenetic associations of Trigonictis within the Mustelidae. Gazin (1934) considered Trigonictis to be closely related to the genus Galictis based on similarities in dental morphology.…”

Postcranial element shape and function: assessing locomotor mode in extant and extinct mustelid carnivorans

Assessment of locomotor modes in fossil taxa must often be made on the basis of heavily fragmented postcranial material. Previous authors have used quantitative methods to determine locomotor function from whole postcranial elements. The goals of this project were to assess the ability of element shape to discern between locomotor modes through landmark analysis, and to apply the results to assessment of fossils. Results suggest that element shape is a good predictor of function, but that different elements have different predictive capacities for each locomotor mode. Additionally, a relationship between size and shape exists that appears to drive morphological differentiation in the group. Finally, data from the extant sample were applied to fossil material of the extinct Plio-Pleistocene taxon Trigonictis . The results suggest that the locomotor mode of Trigonictis was generalized and probably an intermediate between the half-bound locomotion found in weasels and ferrets and the scansorial locomotion of martens and fishers.

“…4,5,8,Tables 1,2). This variability reaches up to 20% of the tooth length (e.g., m1) and appears to indicate the existence of marked sexual dimorphism in the genus, as occurs in other extant and extinct mustelids (e.g., Zakrzewski, 1967;Moors, 1980;Hunt and Skolnick, 1996;Baskin, 1998;Ewer, 1998;Larivi ere and Jennings, 2009). Thus, we believe that sexual dimorphism can help us to interpret the systematics of Eomellivora, and explain the larger size of some Batallones specimens in relation to the material from Turkey.…”

We describe cranial, mandibular, and dental remains of five individuals of the giant mustelid Eomellivora piveteaui Ozansoy, 1965, from the late Miocene (MN10) site of Cerro de los Batallones (Madrid, Spain)-the first complete cranial remains recorded for this species and the most complete remains of the genus. This new sample enables a review of the systematic status of Eomellivora, leading us to accept as valid the species E. piveteaui Ozansoy, 1965, E. wimani Zdansky, 1924, E. ursogulo (Orlov, 1948, and E. hungarica Kretzoi, 1942. Our phylogenetic hypothesis indicates that Eomellivora is the sister taxon of the extant Mellivora capensis and E. piveteaui had a common ancestor within the crown group E. wimani-E. ursogulo. Eomellivora piveteaui was specialized for a more hypercarnivorous diet than the largest extant terrestrial mustelids, although it also had some derived bone-crushing adaptations. Eomellivora piveteaui had an active predatory role in the late Miocene carnivore faunas, exploiting both small and relatively large prey.

“…He also analyzed the fossil horses from the Hagerman and Grand View local faunas; these horses had been a basis for previous estimates of a presumed difference in age. Other recent reports that deal with the mammals are by Campbell (1969), Zakrzewski (1969b), Hibbard (1969), Bjork (1970), and Hibbard and Bjork (1971). Miller and Smith (1967) described seven new species of fishes from the Glenns Ferry Formation, thereby increasing the number of known species to about 20.…”

“…Kepenning (1967, p. 294), however, placed the Hagerman local fauna in the late Blancan (that is, Quaternary) "because * * * several forms * * * appear to be more advanced than those listed from early Blancan faunas." Zakrzewski's (1967) discussion on the systematic position of two species of mustelids Was based on newly discovered skeletal remains and teeth from the Hagerman local fauna.…”

Stratigraphy of the Glenns Ferry Formation from Hammett to Hagerman, Idaho

Lava flows, beds of basaltic pyroclastic material, and layers of silicic volcanic ash that are interbedded in the lake and stream deposits of the Glenns Ferry Formation provide a means for correlating individual stratigraphic sections along the Snake River between Hammett and Hagerman, Idaho. The sequence thus established, composing the lower part of the formation, is more than 1,700 feet thick. A set of columnar diagrams of 60 measured sections graphically shows the lithology of the sections and the positions of petrographic samples and fossil collections. Because the lithology of particular stratigraphic intervals is commonly uniform enough to be assigned to a single sedimentary environment, the set of columnar diagrams shows how the various sedimentary facies overlap and intertongue. Thick sections of lacustrine deposits, for example, were accumulating while flood-plain and fluviatile deposits of an entirely different nature were being deposited nearby. A review of recent reports on the very large and diverse fauna and flora from the Glenns Ferry Formation, particularly the vertebrate fossils, indicates that the stratigraphic sequence described here is late Pliocene. This age is supported by a potassium-argon date of about 3.5 million years.
