A strike in spring would certainly affect temperate regions, but less so the tropics, subtropics and poles. The evidence seems to suggest the C-P extinction event lasted for several tens of thousands of years - ie it was not instant, but drawn out. Which is interesting because the current (Anthropocene) extinction appears to be proceeding much faster than the dinosaur wipeout. But at least crocs and turtles will survive...
I found what I thought at the time was amber on the Little Missouri river in harding cty, south Dakota but after I got home and washed them they looked like tiny turtles in various stages of growth and one the tiny turtles is trying to use his beak to get out of the shell.i think they were from that giant turtle species discovered in western SD. So giant psyunami must have roared up the Western Interior seaway and buried those turtle eggs on the exact day of impact which would be in the spring as stated above around May is what I am thinking.
