As a geologist I want to emphasize how scanty is the exposure of terrestrial(dry land) landscape within the geological record. Assuming we are talking about a terrestrial species, the available geological record is mostly volcanic flows and sand seas (like the Sahara) of huge extent. The surface of the Earth is mostly an erosional surface not a depositional one. Ironically, the best place to find terrestrial fossils is within lake beds (not really terrestrial at all).
As metals do not last on the geological time scale, I think that the most likely evidence would be ceramic fragments or stone structures, but I believe there is too little exposure of suitable habitat and the likelihood of noticing any evidence as might be exposed too slight to say anything about the lack of geological evidence.
- impostervt 9y agoAny idea what the oldest piece of land on earth is that has been continuously dry?
- oldmancoyote 9y agoThe oldest part of the continents are probably what you're looking for. South central Africa, corresponding parts of Brazil, Australia, and parts of eastern Canada are all very old, multiple billions of years old. But really, these are VERY old areas. Lots of things have happened to them in that much time. Some of them were undoubtedly wet.
