Wings are often fossilized, but insect bodies, if present, are usually bits and pieces of the original prehistoric animal, making it difficult for scientists to study them. One way paleontologists learn about prehistoric insects is by trace fossils, which are almost exclusively found as traces on fossil plants. https://phys.org/news/2023-10-unearthing-leaf-miners-ancient-million-year-old.html Evolution Paleontology & Fossils Fri, 06 Oct 2023 13:27:04 EDT news615817622 Snakes are familiar, distinctive—and often feared—reptiles.
