In an image from 2007, they found features that resemble the Mars 3 lander, along with its parachute, heat shield, and terminal retrorocket. The features are the right size and shape for the equipment, and they’re arranged in the configuration expected from the mission’s entry, descent and landing plan, but it’s too early to say for sure whether the photo actually depicts Mars 3..
