The only Hyaenid to access North America: Chasmaporthetes, the βrunning hyena.β I chose to reconstruct it like an aardwolf (Proteles) which might be relatedβlong legs sure look similar. Chasma was more carnivorous but not bone-crushing. Dorsal mane raised to appear bigger. Pliocene #paleoart

Morning with desert gold, also known as desert sunflower, below sea level in Death Valley south of Badwater. Amazing how they grow out of rock-studded barren alluvial fans given a couple of good rainstorms. The Mojave Desert is thriving this year

In almost 30 years of living in and around Death Valley I have never seen the calthaleaf phacelia this dense and abundant, coating the barren rock hills with purple. They are having a banner year in this hyperarid part of the Mojave Desert

Study of Bone-crushing dog Borophagus from the Pliocene of North America. Hat tip to paleoartist Jay Matternes whose Cenozoic mammal reconstructions are amazing. I saw his murals in the Smithsonian when I was a kid, influenced me forever. Pencil on paper π π§ͺ #paleontology

Pelagornis, a giant Tertiary seabird possibly related to ducks. Member of extinct pseudotooth birds, it had bony teeth-projections on jaws. Speculative feeding behavior: dipping for squid as soaring across oceans, or nest predator? This is going into my Pliocene coast painting for a museum #paleoart

This is good. The last time a lake formed in Badwater basin too many people dragged all types of kayaks, canoes, and inner tubes out that they left lasting marks in the delicate salt flat and gouged ruts in the mud. Too munch disturbance.

The diversity of North American Blancan-age Camelids is off the charts: llamas, goat-camels, giraffe-llamas, giant camels. They must have been filling Pliocene niches before the Bovids arrived during the glacials. Pencil size chart; not all may have been contemporaneous #paleoart

Many millions of acres of Western US public lands are seeded with crested wheatgrass, a Eurasian cool-season bunchgrass that is often genetically engineered as cattle forage. Native sagebrush steppe is so much more biodiverse
