Am curious: if dinosaurs can be found with intact skin [1], after 110 million years, why not remains of the civilization's "people" (bones etc.) after 60-50 million years?

- Terr_ 2y agoThey might have just been much better than dinosaurs at not drowning in bogs and other rare fossil-promoting circumstances.
- saberdancer 2y agoAnd number of dinosaurs found compared to number of individual dinosaurs that ever lived is staggeringly low.
- shmeeed 2y agoNot a biologist, but OTOH they might have had a very different body structure that doesn't conserve well, e.g. like molluscs. Or maybe we _did__ find their remains and just have no idea they were part of an intelligent civilization. I mean, that's not a question any respectable researcher would be inclined to raise in the paper about the discovery...
- urspx 2y agoI think the point is that the 'people'/their remains might be findable, but trace or proof of their civilization would not?
