GOD killed the dinosaurs for man's benefit. They died as a result of a major asteroid strike which left a layer of lava rich in Iridium which is a very rare metal. See :

Chicxulub crater
The
Chicxulub Crater at the tip of the
Yucatán Peninsula; the impactor that formed this crater may have caused the dinosaur extinction.
The asteroid collision theory, which was brought to wide attention in 1980 by
Walter Alvarez and colleagues, links the
extinction event at the end of the Cretaceous period to a
bolide impact approximately 65 million years ago. Alvarez
et al. proposed that a sudden increase in
iridium levels, recorded around the world in the period's rock stratum, was direct evidence of the impact.[SUP]
[130][/SUP] The bulk of the evidence now suggests that a
bolide 5 to 15 kilometers (3 to 9 mi) wide hit in the vicinity of the
Yucatán Peninsula (in southeastern
Mexico), creating the approximately 180 km (110 mi)
Chicxulub Crater and triggering the
mass extinction.[SUP]

[132][/SUP] Scientists are not certain whether dinosaurs were thriving or declining before the
impact event. Some scientists propose that the meteorite caused a long and unnatural drop in Earth's atmospheric temperature, while others claim that it would have instead created an unusual heat wave. The consensus among scientists who support this theory is that the impact caused extinctions both directly (by heat from the meteorite impact) and also indirectly (via a worldwide cooling brought about when matter ejected from the impact crater reflected thermal radiation from the sun). Although the speed of extinction cannot be deduced from the fossil record alone, various models suggest that the extinction was extremely rapid, being down to hours rather than years.
