Ancient Dinosaur Feces Unveil an Unanticipated Jurassic Dietary Choice
In a remarkable discovery, a team of international researchers, led by Grzegorz Niedźwiedzki from Uppsala University, have delved into the past to uncover hitherto unknown details about dinosaur diets and habitats. Their findings, published today in the prestigious journal Nature, reveal fascinating insights into the lives of these colossal creatures.
The study focuses on coprolites, fossilized poop and vomit, millions of years old, discovered in sediments from the Early Jurassic in Poland. The team believes that more information may still be hidden in these relics, with millions of years of history potentially locked away in yet-to-be-excavated dinosaur poop and hurl.
Using state-of-the-art synchrotron imaging, the researchers were able to study the internal bits of the coprolites, seeking undigested food remnants. This non-invasive technique allowed them to revisit the coprolites repeatedly, without causing any damage.
Their analysis revealed that the coprolites of large herbivore dinosaurs, such as sauropods, contained ferns, other plants, and charcoal. The team posited that the dinosaurs may have consumed charcoal to protect themselves from toxins that may have been present in the ferns.
Among the plant remains found in the coprolite mass were many whose fossils do not occur in the sites where the coprolites were found, suggesting that the dinosaurs probably fed in a different place than the one where their fossilized feces were discovered.
The team's findings suggest that early dinosaur dominance was a complex transition influenced by factors such as ecological opportunism and competition with other animals. The study also reveals that about 230 million years ago, Poland was part of the supercontinent Pangea.
The team's discovery is significant as it provides a snapshot of the dinosaurs' diet and habitat during the Triassic and Jurassic periods. However, they acknowledge that it will take patience, luck, and a bit of time with the synchrotron to learn more about the days of the dinosaurs through their rejectamenta.
Niedźwiedzki stated that they have something to do for the next 25 years at this site, implying that this is just the beginning of a long and exciting journey into the past. The team's findings also shed light on the dinosaurs' demise, which happened about 150 million years after the moments in deep time captured in the recently interrogated coprolites.
