and f street southeast, someone found a fossil. january of 1898, they think it was a potential ancestor of the tyrannosaurus. the heart of washington, d.c. if you go to the street corner in southeast washington you will see the street sign that bears the name of the dinosaur. unfortunately what they named it is the capitalsarurus, so residents of first streets southeast have the honor of living in a place where a dinosaur was found and embarrassment of living on capitalsaurus court. but the capitalsaurus is the fossil of the district of columbia. lots of u.s. states half fossils. wisconsin has the this creepy 4 millimeter long trylobyte, the jefferson grand sloth.
