Scientists studying the Paja Formation in Colombia have uncovered evidence that ancient oceans were dominated by enormous marine reptiles, some over 10 meters long, filling a previously unseen seventh level at the top of the food chain, unlike today's oceans which typically have six levels of predators.
Fossils from the Paja Formation in Colombia are helping researchers understand the ancient ecosystem that supported a diverse range of apex predators, including massive marine reptiles. By analyzing the size and teeth of various species, researchers are reconstructing the trophic food web of the early Cretaceous period. The findings may offer insights into how the ecosystem flourished after a mass extinction event.
