Fossils are the preserved remains, impressions, or traces of ancient organisms that lived in the past. They can include skeletal remains, shells, leaf imprints, or even footprints. Fossils are typically found in sedimentary rocks, formed from layers of sediment that compact and harden over time, trapping the remains of living organisms. The study of fossils, known as paleontology, provides important insights into the history of life on Earth, including evolutionary processes, ancient environments, and climate changes. Fossils can date back millions of years and serve as crucial evidence for understanding the biological diversity of past eras and the evolutionary links between species.
Recent discoveries in paleontology have offered a fascinating window into the evolution of bird intelligence through the fossil of an ancient bird known as Navaornis hestiae, which dates back around…
