Saurornitholestes
Geological time: Late Cretaceous, 77 - 72 Ma
Found in Alberta, Montana and New Mexico
"The scratched-out burrows provide a unique insight into both the behavior and diet of these dinosaurs, which must have occasionally dug out the burrows of their prey, like many modern predators do. This trace fossil was found in Utah and is dated at around 80 million years old, which means the claw marks could belong to several different small dromaeosaurs or troodonts. I’ve illustrated the dromaeosaur Saurornitholestes here, which was similar in size and anatomy to Velociraptor. The findings were published in the journal Geology.”

Karst landscape geology
"Cutaway artwork showing the features of a karst limestone landscape formed by erosion. The limestone rock has been shaped by natural chemical erosion. Carbon dioxide in the air dissolves in rainwater to form carbonic acid. This acid erodes the limestone rock as the water flows over it. At far right, a river flows down into the ground to form an underground river (across bottom), emerging at lower left. Two layers of caves are shown, with water seeping down from above to form stalactites, stalagmites, which can join to form large pillars. At left, the rock has been exposed, forming a limestone pavement.”
