A group of scientists from Cornell University, among NASA researchers, determined that dinosaurs from the Jurassic period may now exist on other planets. The study was published on: magazine Monthly Notices of the Royal Astronomical Society.
According to the authors, Earth serves as a template for identifying potentially habitable planets. Therefore, by identifying compounds on other planets that existed on the planet at the time of the dinosaurs, scientists can discover analogues of ancient creatures on other space objects.
At that time, oxygen levels on Earth were higher, about 30%, allowing complex creatures to evolve. Currently, oxygen levels on Earth have dropped to 21%. Telescopes will help scientists find planets with high oxygen levels, meaning possible life.
If the planet is in the Phanerozoic phase (a geological period that began about 542 million years ago and continues today), it is the time of “open” life. The beginning of the Phanerozoic eon is considered the Cambrian period. If a sharp increase in the number of biological species and organisms occurred, it is likely to host large and complex life forms.
