How about China? There's a report in New Scientist (No 2341, 4 May 2002, p.28) titled "Killer Blow" about a drilling operation in the Chicxulub crater in Mexico. Among other things it states:

>>
Earlier this year more evidence emerged in support of a gradual extinction.
A team of geologists in China discovered dinosaur eggshells in rock layers
above the K/T boundary. Team leader Zu-kui Zhao of the Chinese Academy of
Sciences in Beijing says this is evidence that some species of dinosaur
survived for 250,000 years after the impact (Palaeogeography, Palaeoclima-
tology, Palaeoecology, vol 1178, p 1).

Does anybody knows more about these findings and their reliabilty?
