Nobody really knows. Two potential sources are the Asteroid Belt, a region between Mars and Jupiter, and the Oort Cloud, a region beyond Pluto. See links below.
The Chicxulub crater lies buried, straddling the northwest coastline of the Yucatán peninsula
Scientists usually refer to this as an asteroid, not a comet. It's the asteroid that caused the Chicxulub crater.
It is the asteroid that hit the Earth 65 million years ago and contributed to the extinction of the dinosaurs. It impact crater is located in Chicxulub which is in the Yucatan peninsula, it is buried deep underground. KT refers to the geological transition between the Cretaceous and the Tertiary periods. (Cretaceous in German starts with a K)
An uncommon belt of dust with radioactive elements is found just where many dinosaur remains cease to be found (chronologically speaking). The layer of dust corresponds to an impact of a giant asteroid in what is now the Gulf of Mexico called the Chicxulub crater, just north of the Yucatan peninsula.
The Chicxulub Crater is located near the city Chicxulub in Mexico. This crater is approximately 66 million years old and discovered by Antonio Camago and Glenn Penfield in the late 1970's.

The Chicxulub crater is the area in the state of Yucatan that was hit by an asteroid. It is about 66 million years old.

rocks of dust :)like a big rock with holes in themor a big pile of space dust combine togetherand probably another asteroid hit the Chicxulub asteroid whic cause it to come to earth:(

The Chicxulub asteroid, which hit the Gulf of Mexico about 65 million years ago. It is said to be the asteroid that killed the dinosaurs.
Both locations are wrong. The Chicxulub asteroid landed on the Yucatan Peninsula, in the country of Mexico, more than 2,283 kilometers (1,418 miles) southeast of New Mexico and 3,812 kilometers (2,369 miles) southwest of Haiti.
The Chicxulub Asteroid impact caused the dinosaur extinction, evidence of which the K2 boundary illustrates.
Apophis is an 885 foot diameter asteroid that will pass by Earth on April 13, 2036. The odds of it hitting the Earth are calculated to be 1 in 48,000. Keep in mind that the asteroid that crashed into Chicxulub, Mexico wiping out the dinosaurs was 6 miles wide,nearly 36 times larger.
The September 11 attacksansw2. Perhaps the asteroid impact at the K/T boundary - in the Yucatan Peninsula of Mexico. The Chicxulub crater, about 65 million years ago.
