What do you think about these tiny fossils ?
Hatchet posted a topic in Fossil IDI have found it within Eocene clastic and carbonate rocks. The rock is some clastic rock with high carbonate context. I am thinking maybe the white fossils in the rock are some kind of nummulites. What do you think ?

NASA's Mars 2020 Will Hunt for Microscopic Fossils
Heteromorph posted a topic in Fossil NewsThe 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
