November 30 - December 4

This week in Biology, we had learned two new packets of information about energy and cellular respiration. We had a quiz over these topics and also had a lab concerning exercise and cellular respiration. This lab was very fun and interesting because we got to be physically active by doing moderate to intense exercise and seeing how it effected carbon dioxide output (and oxygen input). We learned that during exercise, we breathe in more oxygen and exhale more carbon dioxide than we do at rest.

Article of The Week (November 30 - December 4)

This article talks about the discovery of a rare fossil found in Eastern North America. The fossil was identified as a dog-sized horned dinosaur and distant relative from the triceratops. Because it is a ceratopsian dinosaur from this period of eastern North America, it is unique and will probably help in future research. According to the article, the specimen studied by Longrich was too incomplete to identify the exact species accurately, but showed a strange twist to the jaw, causing the teeth to curve downward and outwards in a beak shape.  

In my opinion, we should try to find other fossils from this dinosaur by exploring the region in which it was found. Although the area is mostly covered by trees and might hurt the excavation, this might not be an option. So, if it is possible, we need to explore this part of the world. In addition, this might be an undiscovered dinosaur because its likes have never been seen before and it was unable to be identified. This gives more reason to explore the "lost continent", as it is referred to by the author of the article.  

A quote that stuck out to me was this, "Each one of these island continents would have evolved its own unique dinosaurs- so there are probably many more species out there to find." How can they say that there are plenty of unique dinosaurs that are undiscovered and do nothing about it? If researched, these dinosaurs might bring about amazing discoveries in science. Another quote was this, "At the time, many land masses -- eastern North America, Europe, Africa, South America, India, and Australia -- were isolated by water". This makes me wonder how many undiscovered fossils there are under water in the vast ocean.  

This article leaves me with one question: Is finding new dinosaurs worth the trouble of excavating? If so, what would it take to explore unexplored regions to find them?
