Vector illustration of Antilohyrax pectidens, a small cursorial Titanohyrachid from the Oligocene of Egypt, grooming its front leg. This hyrax relative looks somewhat like long-snouted hyrax with long thin legs. It is greyish in color, with dark and light patches on its legs, rump and face, and a bright yellow stripe on its back

Vector illustration of Pakicetus attocki, a bizarre early whale relative, laying on its stomach looking at the viewer. This strange animal has long legs with hooved feet, a thick hairless tail, small ears and a long, narrow skull lined with sharp teeth for catching fish and other small animals. Its eyes are positioned up at the top of the skull as in hippos to see over the water line. The artiodactyl is reddish brown with a lighter underside

Rounding out our trip to the mid Eocene Kuldana formation with another stem cetacean, Pakicetus attocki #marchofthemammals2026

Result from the Wadi al Hitan #paleostream!
The "valley of the whales" as it is better known is a classic locality from the late Eocene of Egypt. Most famously it is place filled with the remains of early whales, Archaeoceti, but it's less straight forward as a piece than one...

A black-and-white pencil sketch of a shark, Physogaleus, nibbling on the tattered edge of a severed head of the whale Basilosaurus. The large head is lying on its side on the seafloor with mouth wide open, while the shark’s body is very curvy as it attempts to slice off a bite. Near the head on the seafloor is a much smaller crab.

Quick sketch of the tiger-shark-cousin Physogaleus nibbling on the severed head of what would normally be its predator, Basilosaurus. A scene in the shallow waters of late Eocene Egypt, sketched during the Wadi-El-Hitan formation #Paleostream. #paleoart #sciart #shark #whale

Vector illustration of Anthracobune wardii, a large bodied stem-perissodactyl from middle Eocene South Asia. The large, stocky, tapir like animal is sitting on its haunches looking up. It is dark brown with a dark underside, with dark stripes on its long tail and white patches on its legs and face

Black and white ink line drawing of a stylized flying great horned owl on a black background. The black background has a white circle where the owl's legs are. There's a text under the drawing that says "mooncatcher".

Sometimes I draw traditionally too

Vector illustration of Jurassic multituberculate Rugosodon eurasiaticus, climbing on the curved branch of Wielandiella, a bennittitale. The rat like allotherian mammal is brown-grey in color with a light underbelly and light spots on its brow. Wielandiella has long curving branches lined with leaf scars, topped with a crown of long, draping leaves. There is a large orange fruiting body in between the branches, dotted with a rough texture
