Scientific analysis of dinosaur extinction is caused by a comet

In Washington, a group of scientists said that a comet caused the extinction of dinosaurs 65 million years.
Experts at Dartmouth College in New Hampshire, based on their findings, analyzed soil geochemistry at the Hicksulubi Crater, a 180 km wide Yucatan peninsula located in Mexico. The generally accepted theory is that A large planet caused the death of these animals and ruled the Earth for millions of years. However, the research team led by Jason Moore stated that it is a non-cyclical comet, leading to its extinction. Such object balls of dust, rocks and ice travel eccentrically around the sun and delay hundreds, thousands, or even billions of years to complete an orbit.
The results of the Lunar and Planetary Sciences conference held in Texas on the basis of the comparison of the United States level, with other chemicals found in the bottom of the pit from the outer space of the helium and cockroaches. According to scientists, the estimated concentration of plutonium is incorrect in Chicxulub. Began to recalculate the level of chemicals, scientists believe that the Earth's impact on the body is smaller than you think. The second part of the study attempts to compare the effects of new data with known physical properties to create a crater. According to scientists, such a big hole, an institution can be faster and smaller as a cycle comet, rather than an asteroid's movement is slow. "It will take about five kilometers to achieve the diameter of the asteroid, the amount of plutonium and plutonium. But the size does not make a crater 200 kilometers.
This study is very interesting, but I believe it is impossible to accurately determine the size of the body through geochemistry. According to these experts, the Germans believe that geochemistry to determine the quality of materials distributed globally does not affect the body.
