Dr. Charles Schuchert Traces Rise of Dinosaur. "Animated citadels of flesh, with nothing to fear but themselves, two pounds of brains to 76,000 pounds of flesh," brute strength and low mentality." These, according to Professor Charles Schuchert, are among the characteristics of the great reptiles of the medieval world. The medieval time in the world's history, he stated in his lecture at the university Friday night, was pre-eminentlly the heyday of reptiles. During that era reptiles held possession of the earth; in the air were great dragons with expanse of wing of 25 feet; in the waters were fish-like reptiles of great size; while on the land the dinosaurs, "terrible reptiles," held sway. The dinosaurs, according to Professor Schuchert, include the most extraordinary animals that the world has seen and the largest land animals that have lived. One of these, called Egiandinosaurus, "gigantic saurian," has a length of 80 feet, 36 feet of which is neck. Another, brontosaurus, "thundering saurian," had a length of 65 feet, weighed about 37 tons and required a daily ration of probably 700 pounds. Among the vegetable feeders were some having no more than one pound of brain to 80,000 pounds of flesh, or "enough sense to eat when hungry." Traces Reign of Dinosaur. The disappearance of the dinosaurs from the earth coincides with the great mountain-making period which gave rise to our rocky mountain system. They occupied the whole of medieval time. "Their career," says Professor Schuchert, "was not brief and is comparable in majestic rise, slow culmination and dramatic fall to the great nations of antiquity." In the latter part of the reign of reptiles the mammals made their appearance at first few in number and small in size, but representing an immense advance in brain capacity. The next and final lecture of the series, on "The History of the World," will be given in K hall at 7:30 p. m., Monday, March 8. Professor Schuchert's subject will be "The Dawning of Present Scenery and Life." The lecture will be open to the general public.
