But when fossilization is rare, why are there so many dead things in such a small area that ended up being buried in such a short space of time that fossilization happened and we have such treasures? What, precisely, happened at Hell Creek 66 million years ago to cause this monster fossil bed?

[@muddigs5887]

It was in the Eastern Seaway so when everything died it got washed down the water to an area and when the asteroid hit it killed a lot of animals and since it was in the water with a lot of sediment that would help it fossilize and become the hell creek formation.

[@bigal4109]

It was due to waves created Oceanside after the KT extinction event. The it event caused worldwide earthquakes up to a magnitude 11.5 earthquake. This causes waves of preposterous sizes even before the mega tsunamis afterwards within the 24 hours of the impact this caused the dinosaurs and fish that where killed to be washed inshore into large groups under sediment and the ensuing tsunamis caused additional sediments to be compacted on top not only allowing for such mass fossil counts in the area but for the fossils to be of such high quality

@@bigal4109 so they died by drowning of the tsunami

[@bigal4109]

Ignacio A no they died do to Sieche waves caused by an earthquake the following tsunami covered the corpses in a thick layer of sediment which is why most specimens are so well conserved

A flood?

underneath that turtle , is her earth.............. do you grab dirt samples , for spores? you could take a quick look and tell us with microscope , what you see.................and always tell the climate and vegetation of the bone owners time. repetition is good. but quick.
