Courtesy Mark RyanToday marks the birthday of Arthur Lakes (1844-1917), a geologist, artist, and teacher who discovered some of the first dinosaur remains in the western United States. During the spring of 1877, Lakes was out measuring rock formations above Morrison, Colorado when he and companion John Beckwith stumbled upon the huge fossilized bones of dinosaurs. When Lakes sent samples to Yale paleontologist Othniel Marsh, it started the great western bone rush that would soon escalate into the infamous Bone Wars between Marsh and his arch-rival Edward Drinker Cope. While in Marsh's employ, Lakes created several iconic watercolor paintings of the diggings that occurred in Morrison, and later at Como Bluff in Wyoming. You can read more about Lakes in a post I made last year on his birthday.
