Could things that look like fossils trick us thinking there was once life on Mars? If you want to believe, fake Martian fossils might convince you (but they're just rock formations).

Perseverance Rover Lands Safely - Will Search for Ancient Life on Mars
Oxytropidoceras posted a topic in Fossil News
NASA Lands the Perseverance Rover on Mars The science mission will launch the first drone to fly on another planet, attempt making oxygen in space, and search for signs of ancient life. Sarah Scoles, Wired, February 18, 2021 NASA's Perseverance rover landing on Mars, PBS Yours Paul H. -
The rock in the image was actually found on Mars. I know it's probably not a fossil as NASA has addressed this saying it was likely formed by water and wind erosion. Please don't take this post the wrong way. I am not interested in perpetuating anything unscientific. I am just curious about the topic; how we can analyze rocks like these found on another planet. If one were on the team, and we spot something like this, to the untrained eye it would look like an astonishing find. But we have to be objective, and we have no idea what fossils on Mars might look like, in the unlikely case they actu

The search for extra-terrestrial fossils is looking more promising. But, I suppose one mustn’t get one’s hopes too high. NASA's Mars 2020 Will Hunt for Microscopic Fossils “Scientists with NASA's Mars 2020 rover have discovered what may be one of the best places to look for signs of ancient life in Jezero Crater, where the rover will land on Feb. 18, 2021. A paper published today in the journal Icarus identifies distinct deposits of minerals called carbonates along the inner rim of Jezero, the site of a lake more than 3.5 billion years ago. On Earth, carbona
