Yes! There are loads and loads of places where sedimentary layers are well exposed, probably more exposures than Earth given that most sedimentary rocks on Earth are buried by soil/vegetation/water.

Valles Marineris is the biggest example, it's a canyon 3 times deeper than the Grand Canyon and is so long it would stretch across the whole of America.

This page has dozens of pictures of cliff faces with layered rock in Valles Marineris

Here's one cool example. Maybe there are fossils there! We'd need to send a new rover or helicopter to find out :)
