The guy group in the period three advanced biology class did their project on the Tylosaurus. The Tylosaurus was a water predator that lived millions of years ago. The Tylosaurus was over fifteen meters long. It is also called the knob lizard. It had a large diet. The Tylosaurus would eat its body weight every meal. The Tylosaurus would hunt by lurking in the depths of the ocean. It would wait for prey to come along and then it would charge through the waters and strike the prey unconscious with its snout. Then while the prey was dazed the Tylosaurus would attack the prey and eat it. This theory is proven by the damage shown in the bones of the snout of the Tylosaurus.
The process of making the fossil of the Tylosaurus took a lot of time. It took hard work and many hours, including coming in at 6:00 o’clock in the morning for the guys. The Tylosaurus has 245 bones. It took a lot of time and effort to cut them out and put them up. This is a picture of one of the greatest predators, the tylosaurus.
The sophomore girls of the third period Advanced Biology class spent about a month creating a life size skeleton of a Steller Sea Lion. We started off by printing off a diagram of the bones and found the ratio of the picture bones to a life size bone. After we found the measurement of bones we would draw them on a big piece of brown paper. We would cut the bones out piece by piece. There were a total of 110 bones. We would hang these bones up on the ramp in our school for the elementary to see. Along with the bones we hung up two pictures of the sea lion and a plaque describing the animal for everyone to read.
The Steller Sea Lion is also known as the Northern Sea Lion. They can weigh up to 2,500 pound, live up to 20 years of age, and range in length from 10-11 feet. These animals rang in color from tan to dark brown. These animals live in subarctic waters. They only would come to land during mating season. The places on the beach are called rookeries where males try to attract females for reproduction. We named our life size Steller Sea Lion skeleton Norman.
