In this video we’ll travel back to the world of the early Jurassic and take a modern look at it’s most iconic dinosaur: Dilophosaurus. By studying the latest specimens, fascinating fossils from the world Dilophosaurus lived and evolved in, and modern biology, paleontologists are just now starting to get a clearer picture of this important period in dinosaur evolution and the history of our planet.

This video is the culmination of about 5 years of communication and collaboration with Dr. Adam Marsh (@NotThatMarsh) who has been studying #Dilophosaurus for the past 6 years, and who recently published a comprehensive description & analysis of this important dinosaur.

Over the last several years I have had the good fortune to be able to create numerous pieces of art centered around Dilophosaurus and the world it evolved in thanks to the St. George Dinosaur Discovery Site and The Las Vegas Natural History Museum which have commissioned me to create numerous pieces of art depicting life in the early Jurassic.

This video also features art commissioned by paleontologist ReBecca Hunt-Foster through funding from Utah BLM / Utah Friends of Paleontology. The scene depicting an early Jurassic tracksite was created for an interpretive panel now at the Poison Spider Dinosaur Tracksite near Moab Utah. You can explore this fascinating early Jurassic tracksite (for free) on your public lands near Moab Utah. More information here:

The End Triassic extinction, and the recovery of earth’s ecologies that followed in the early Jurassic is a really important time for us to study because it relates directly to climate change. The latest data from geology, paleobotany and paleontology suggests that a huge catestrophic extinction that ended the Triassic period was brought about by a sudden increase in atmospheric CO2 which cause runaway global warming and ocean acidification. While the CO2 spike at the end of the Triassic was caused by volcanic eruptions in what is now the central Atlanic cooking through a bunch of marine carbonate rocks and releasing the vast ammounts of CO2 stored in them, the latest data indicates that the rate of CO2 flooding into the atmosphere was about the same as the rate at which humans are flooding the atmosphere with CO2 by burning carbon-rich fossil fuels. This is really really scary. You should be shook. This extinction wiped out many of the most badass toothy, gnarly, armored prehistoric monsters that have ever lived. Here are a few links to get you started on your journey of understanding extinction and the role we play in it:
