PASSAGE 1 – Questions 1-10
It was previously believed that dinosaurs were cold-blooded creatures, like reptiles. However, a recent discovery has led researchers to believe they may have been warm-blooded. The fossilized remains of a 66 million-year-old dinosaur’s heart were discovered and examined by x-ray. The basis for the analysis that they were warm-blooded is the number of chambers in the heart as well as the existence of a single aorta.
Most reptiles have three chambers in their hearts, although some do have four. But those that have four chambers, such as the crocodile, have two arteries to mix the oxygen-heavy blood with oxygen-lean blood. Reptiles are cold-blooded, meaning that they are dependent on the environment for body heat. Yet the fossilized heart had four chambers in the heart as well as a single aorta. The single aorta means that the oxygen-rich blood was completely separated from the oxygen-poor blood and sent through the aorta to all parts of the body.
Mammals, on the other hand, are warm-blooded, meaning that they generate their own body heat and are thus more tolerant of temperature extremes. Birds and mammals, because they are warm blooded, move more swiftly and have greater physical endurance than reptiles.
Scientists believe that the evidence now points to the idea that all dinosaurs were actually warm-blooded. Ironically, the particular dinosaur in which the discovery was made was a Tescelosaurus, which translates to “marvelous lizard”. A lizard, of course, is a reptile.
