The "Tanis" site of the Hell's Creek formation in North Dakota preserves the immediate hellish hours after the asteroid impact 66 million years ago.

The location is a riverbed where the M10-M11 earthquake caused by the impact (thousands of kilometers away) resulted in a massive "seiche" standing wave, leading to an apocalyptic die-off of plant and animal life, as the river's flow was reversed multiple times similar to a tsunami. Fish gasped for air in their final moments as their gills were filled with sand and small globules of glass that were lifted by the impact from the Yucatan peninsula and rained down in North Dakota like hail and snow. Marine life from the Western Interior Seaway was pushed upstream and mixed with the freshwater fish, all dying within a short period of time. Ash, charred plants and globs of amber indicate the nearby forest was on fire at the same time, and the location is topped by the iridium layer characteristic of the K-T extinction event.

The massive number of fossils were well-preserved in 3D despite being only lightly covered in the immediate aftermath of the impact, showing that no scavenging happened in the near-lifeless hellscape world of the newborn Cenozoic era. A tiny ratlike mammal's burrow was found cutting through the extinction event boundary, with its digger's remains still inside after it died alone in the freezing darkness.

>tl;dr: Most important find regarding the KT asteroid impact since the identification of the Chicxulub crater in the 80's.

First paper, probably of many to be published. Only a ceratopsian hip bone was published in this one, but other dinosaur fossils like raptor feathers have already been found:

That's just fucking crazy. That site will still give us new insights when I'm in a home for the elderly.
