A lounging blue Tyrannosaur stares out of a hazy electric green jungle across a lazy stream on a warm afternoon in late summer. Although I was more interested in exploring color and patterns rather than exploring science with this painting, I also included some recent findings on Tyrannosaur skin covering and compared the bone textures on the skull with the skulls of crocodiles and birds - Tyrannosaurus rex's smaller cousin Daspletosaurus horneri seems to have sported a tactile snout, not unlike a crocodile's, complete with sensory pits called "foramina". As fond as I am of the idea of all kin of Tyrannosaurus sporting at least some sparse coat of feathers, I must concede that there is no evidence to support such on the larger members of the family tree, and other skin impressions hint at large Tyrannosaurs, especially those in southern climates, were more scaly "murdercrocs" rather than my preferred "murderbirds". Scaly T. rexes are "back", scientifically speaking - for now. For this reason, I felt a desire to evoke the hazy, nostalgic color palettes, themes, and patterns associated with the "Vaporwave" art and music movement as seen through the lens of "deep time". The coloration and pattern, though fantastically and speculatively garish, is also somewhat rooted in science - Bob Nicholls' 2016 Psittacosaurus sculpture and subsequent co-authored scientific paper discusses a coat pattern known as "countershading" - combinations of light and dark colors that break up an animal's outline, usually involving the lighter color on the belly and the darker color on top.

Flower Dance raven Sat, 5 May 2018 - 23:29

Body

An electric blue Parksosaurus warreni “dances” among a wide variety of flowering plants known from different locations across Alaska and Russia during the Cretaceous era. While we are most familiar with the Pleistocene-era Bering land bridge connecting North America and Eurasia, evidence of many shared fossil plant and animal species show Alaska also bridged the continents during the late Cretaceous. Plant fossils across the arctic point to a warm, dense forest that covered the northern extreme of both continents, brimming with many flowering plant species and a wide diversity of fauna.

Body

A female Nanuqsaurus took a strange turn along the ancestral Colville River and finds herself feeling very small indeed among the towering giant plants of an ancient garden forgotten by time - a remnant of a warmer, wetter period of Alaska dominated by ferns, cycads, Bennettitales, dawn redwoods, and Ginkgoes, with interloping stands of flowering ginger plants as a reminder of the changing order of things.

This is currently available as a large signed canvas print at Bigfoot Art Gallery in Palmer, AK.

Body

Fossil footprints found in Denali National Park revealed that at least two species of pterosaur (ancient flying reptiles that were "cousins" to dinosaurs) roamed the north lands and flew the chilly skies of Cretaceous Alaska around 70 million years ago. Pictured here is the larger of the two species recorded - a large azhdarchid modeled after Quetzalcoatlus.

Fishing In The Land Of Giants raven Tue, 15 Aug 2017 - 13:48

Body

A scene of the estuaries of Pleistocene era California depicting a scavenging short-faced bear, Arctodus simus, feeding off a spawned-out female Oncorhynchus rastrosus, the "saber-toothed" salmon, with an entourage of ancestral California gulls, Larus californicus. In the water, a pair of speculative ocean-phase Oncorhynchus enters the estuary looking for food, while a pair of spawning males jockey for status and position, ready to meet their fate upstream.

Originally produced for Dr. Darren Naish's book-in-progress about the vertebrate fossil record.Scene depicting Pleistocene California with Oncorhynchus rastrosus, Arctodus simus, and Larus californicus.
