In a recent study published in the Monthly Notices of the Royal Astronomical Society, researchers have proposed the possibility of alien dinosaurs existing on other planets. The study suggests that these extraterrestrial dinosaurs should be considered in the search for life beyond Earth.
The research points to the high levels of oxygen during the dinosaur era, reaching 30% compared to the current 21%. This elevated oxygen level is believed to have contributed to the massive sizes of many prehistoric creatures. The researchers propose examining planets with similar oxygen levels and expanding the search to include other “extinct” compounds. This approach could enhance the chances of discovering planets capable of harboring complex life forms, similar to the dinosaurs of Earth.
Lead author Rebecca Payne explains, “The Phanerozoic represents only about the last 12% of Earth’s history, but it encompasses nearly all of the time when life was more complex than microbes and sponges. These faint chemical signatures are what you would look for elsewhere if you were searching for something more advanced than a single-celled organism. And who knows, maybe there are other dinosaurs waiting to be found out there.”
The study highlights the need to seek signs of a Phanerozoic stage – the eon spanning the past 541 million years, during which animal and plant life proliferated on Earth. The researchers advise looking for these chemical signatures on other planets in the search for advanced life forms.
When considering the grand scheme of Earth’s history, humans represent a mere speck, accounting for just 0.000001% of the planet’s biological history. The study stresses that life on other planets may have also gone through arduous evolutionary processes spanning millions or billions of years before attaining advanced forms.
Recent research aligns with the notion that alien dinosaurs are not only a possibility on other planets but should actively be considered in the search for extraterrestrial life. The findings of this research raise important questions about the potential existence of complex life forms beyond Earth.
