This is one of my favorite YEC stumpers. 
It’s a site in Bolivia with a 300’ tall almost vertical limestone wall covered with dinosaur tracks. Over 5000 footprints total in over 400 distinct tracks from at least 8 different species. The area was a flat tidal basin 68 MYA when the dinos trod there. Over time it was covered under additional sediment and lithified, then plate tectonics lifted and tilted the whole slab and which was recently exposed by a combination of erosion and quarrying in the area.
Lots more photos can be seen here

I’m told the Creationists are “looking for mechanisms”.
