The end of the Cretaceous World and its fossil

   Numerous fossilized dinosaur eggs have been found along the Toyo-river, Aichi-prefecture, Japan. Fossilized dinosaur eggs vary in size markedly. Dinosaur might have laid bigger eggs as they become older. They are often found compressed and partially broken durring the process of fossilization and their eggshells are also partially scraped and torn away. Judging from appearance of the edge of the broken eggshells, it seems they are not like chicken eggshells but morelike turtle eggshells.



  Numerous fossilized dinosaur feces have been also found. They are white or black. The white feces are like balls of fiber. So it is considered they are herbivorous dinosaur feces. On the other hand, the black feces are rather small in size and contain small amount of fiber on their surfaces. So it is considered they are carnivorous dinosaur feces. 





  A lot of fossilized dinosaur testicles have been also found. Recently, I found an unbelievably big fossilized dinosaur testicle. Note blood vessel like strusture runs on the surface of the fossil whitch is characteristic of the testicle. The other fossilized testicle are shown here. A piece of a ceramic tile is 20 by 20 square centimeters.
