“…If the jerboa remains described here are properly interpreted as evidence of the diet of F. hezhengensis, as we suggest, they and the unique hindlimb proportions in the new species may indicate a shift in kestrel diet and ecology between the Late Miocene and the present day. Such a shift would be consistent with previously reported Late Neogene turnover and environmental change in these steppe communities , Zhang 2006, Song et al 2007, Kurochkin et al 2010.…”

“…Seasonal variation in northwestern China is estimated to have begun increasing in the Late Miocene, related to increased monsoonal intensity and Himalayan uplift (Song et al 2007). The Late Pleistocene disappearance of ostriches from the Asian steppes (Kurochkin et al 2010) as well as possible shifts in predator-prey relationships further support significant recent changes in the avifauna of these arid steppe environments. Today, jerboas have been reported to be the primary prey of the Little Owl (Athene noctua) in Central Asia (Lay 1974); they have not been described as part of the common diet of any extant kestrel species.…”

Although the family Falconidae, which includes extant falcons and caracaras, has a long evolutionary history, most previously reported fossils referred to this family are isolated single elements. We report a new species, Falco hezhengensis sp. nov., represented by a nearly complete and articulated skeleton from the Late Miocene deposits of Linxia Basin in northwestern China. The new fossil shares an array of derived morphologies with the genus Falco, and analysis of the largest morphological dataset for Falconidae, sampling most genera, identifies the specimen as a new stem kestrel. The phylogeny shows a high degree of congruence with published molecular phylogenies and time trees supporting a Miocene radiation of Falconidae. The species provides a new calibration for the divergence of extant kestrels from other Falco. Remains of a small mammal, a jerboa (Dipodidae), are preserved in the abdominal region of the specimen. Integrated with data from other avian remains from the Linxia Basin, the new fossil provides further support for changes in the open steppe environment of Central Asia since the Late Miocene. Changes in falconid ecology and diet, shifts in small-mammal abundances, as well as the extinction of the Central Asian ostrich may be involved in community turnover in the Late Neogene. Keywords: Aves, Falco, fossil, jerboa, Late Miocene, Linxia Basin Un Falcónido del Mioceno tardío del noroeste de China brinda evidencia adicional de la transición en las comunidades de estepa del Neógeno tardío RESUMEN Aunque los Falconidae, que incluye halcones y caracaras vivientes, tienen una larga historia evolutiva, la mayoría de los fósiles previamente reportados para esta familia son elementosúnicos aislados. Aquí reportamos una nueva especie, Falco hezhengensis sp. nov., representada por un esqueleto casi completo y articulado de los depósitos del Mioceno tardío de la Cuenca de Linxia en el noroeste de China. El nuevo fósil comparte un conjunto de morfologías derivadas con el género Falco, y el análisis de la mayor base de datos morfológicos para Falconidae, con muestras de la mayoría de los géneros, identifica el espécimen como un nuevo cernícalo basal. La filogenia muestra un alto grado de congruencia con las filogenias moleculares y los árboles de tiempo publicados que apoyan una radiación de Falconidae en el Mioceno. La especie brinda una nueva calibración para la divergencia entre los cernícalos vivientes y el resto de los Falco. Los restos de un pequeño mamífero, un gerbo (Dipodidae), están preservados en la región abdominal del espécimen. En conjunto con datos de otros restos de aves de la Cuenca de Linxia, el nuevo fósil brinda sustento adicional para los cambios en el ambiente de estepa abierta de Asia Central desde el Mioceno tardío. Los cambios en la ecología y la dieta de los falcónidos, las fluctuaciones en la abundancia de los pequeños mamíferos, así como la extinción del avestruz de Asia Central pueden estar involucrados en el recambio comunitario del Neógeno tardío.

“…In northern Mongolia, ostrich-which in North Asia required an arid steppe environment-may have lasted until 8.9 cal yr ka BP [46,47]. The ostriches at Aral Tolgoi indicate the previous existence in that region of dry grassland and xeric vegetation, while the rhinoceros image-like the mammoths from TS/BO-indicates a contemporary cold steppe environment.…”

Rock-pecked images from the northern Mongolian Altai attest to the presence of human communities within the high valleys of that region during the Late Pleistocene and Early Holocene. The material provides evidence that is hitherto largely missing from the archaeological record of that region. This paper reviews the rock art, its find sites and larger physical contexts and uses evidence from paleoenvironmental studies to propose dating and cultural significance. The material is compared with other sites said to have Paleolithic imagery from Mongolia and the adjoining Russian Altai. The body of presented material offers a major resource for the study of early hunter-gatherer communities at the interface of Central and North Asia.
