Dire wolf (Canis dirus) illustration based on skeletal mounts at Rancho La Brea, and colors of various living Canids. Digital.
A book project I am researching, writing, and illustrating, is a deep guide to the of the Ice Age of Western North America. This is a project long in the making, and I have been illustrating the various megafauna and Pleistocene scenes for decades. The book will focus on the Rancholabrean Land Mammal Age, and will be my paleoart view of traveling back in time to this lost world

Pencil sketches and notes on the new paleontological discovery rocked the world: a frozen mummy of a Homotherium latidens cub with fur and other soft tissues was found in Pleistocene permafrost Yakutia (northeastern Siberia) was described in a scientific paper published in the journal Nature. This was a monumental find: the first Machairodont sabertooth cat frozen carcass described, revealing significant new information about the fur, coloration, paw structure, and other soft tissues that have only been the subject of speculation before this. Lopatin et al. (2024) reported that in 2020 a frozen mummy of a large carnivore cub was found in in Siberia, Russian Federation, along the Badyarikha River in a deposit with mammoth bones in a loess-loam horizon (perhaps a Mammoth Steppe habitat.) The radiocarbon date based on wooly fur is about 31,000 years before present, calibrated to about 35,000 to 37,000 years before present. The frozen mummy of the felid cub includes the head and anterior part of the body, and a few other pelvic bones.

In this sketch I added color with colored pencils. The cub has an overall dark brown hue, but with tones of burnt umber and red ochre. Light cream-colored highlights exist on the eyelids, the tip of the nose, chin, and underside of the jaw including the long hair tufts, as well as extending in a small area down the neck. A few lighter-colored hairs can be seen on the cheek scruff and in the ear. After the photo in Lopatin et al. (2024).

San Francisco Bay 40,000 years ago showing to dry valley looking westwards through the Golden Gate past the hill Alcatraz. Ancient bison (Bison antiquus) and Western horse (Equus occidentalis) graze in grasslands of purple needlegrass (Nassella pulchra) and California oatgrass (Danthonia californica) grow with parklands and forests of coast live oak (Quercus agrifolia) and Douglas fir (Pseudotsuga menziesii). Late spring white tarweeds (Madia) dot the ground. A segde (Carex tumulicola) swale is on the lower right. Calidoenia ground squirrels (Otospermophilus beecheyi) also graze. Acrylic on paper.
