"US  palaeontologist amasses data against Mexican crater  hypothesis."

"New cores drilled in east Texas could upset the  Chicxulub theory."

"The widely held theory that a particular meteorite strike on Mexico  wiped 
out the dinosaurs is under sharp attack, again."
 
"The asteroid that created the Chicxulub crater in the Yucatán peninsula in  
Mexico arrived too early to have caused the Cretaceous-Tertiary mass 
extinction,  according to evidence given on 23 May at an American Geophysical 
Union  
conference in New Orleans, Louisiana."
 
"A team led by palaeontologist Gerta Keller of Princeton University, New  
Jersey, reported that a sediment core drilled in east Texas emphatically  
confirms a study that the group released two years ago. Sediments of glass  
sprayed 
out by the Chicxulub impact are separated from fossils killed during the  mass 
extinction by a 300,000-year gap, they argue."
