Danielb Posted June 5, 2023 Share Posted June 5, 2023 (edited) Hi I was on a friends property near Boulder and golden Colorado and found ripples from water. When I looked closer it looked like there were scratch marks possibly from a dinosaur. When I looked on a geologic map it said the age was creatacous. I’m just wondering if it could possibly be scratch marks from the beasts the used to wander the earth. I think the formation is the Dakota formation. Any help would be appreciated.

Desrosiers1718 Posted June 5, 2023 Share Posted June 5, 2023 Looks like weathering to the rock over the years. Link to comment Share on other sites More sharing options...
jpc Posted June 5, 2023 Share Posted June 5, 2023 (edited) certainly ripple marks... sandy bottom of a beach environment. The scratch marks seem pretty subtle. There are dozens if not hundreds of critters that leave traces in shallow sand bottoms. Dinosaur, maybe, but much more likely some sort of marine invertebrates. Rolling pebbles and seaweed tossed about by waves can also leave marks. And as mentioned above, it could also be erosional.
