Celebrating the 107th anniversary of Earl Douglass' first dinosaur fossil discovery on this date! After several days toiling in the hot desert sun searching for dinosaur fossils, Paleontologist Earl Douglass was feeling rather discouraged. But despite his frustrations, Douglass' longtime vision of finding a complete skeleton persisted, giving him hope and inspiring him to continue his search. Douglass' journal entry August 17th, 1909: "I began searching the hard sandstone which are unusually thick and well exposed there...and found lots of broken and shattered bones but as usual, nothing perfect. At last, in the top of the ledge where the softer overlying beds form a divide, a kind of saddle, I saw eight of the tail bones of a Brontosaurus [Apatosaurus] in exact position. It was a beautiful sight. It is by far the best looking dinosaur prospect I have ever found. The part exposed is worth preserving anyway." Unbeknownst to Douglass, the eight tail bones he found would lead him to a colossal dinosaur graveyard - one that would become world-famous. Nor did he know that he would spend the next 14 years of his life removing nearly 350 tons of dinosaur bones. #dinosaurnps #findyourpark #encuentrasuparque #nps100 (at Dinosaur National Monument)
