The Evolution of Human Dietary Patterns Biology Diagrams The discovery adds to growing evidence suggesting that marine food chains millions of years ago operated similarly to those we observe today, with predators and scavengers playing distinct but interconnected roles in their ecosystems. This 15-million-year-old specimen provides a rare glimpse into these ancient ecological relationships Researchers uncovered a prehistoric ecosystem teeming with giant marine reptiles, uncovering unmatched food web complexity Predators at the top of a marine food chain 130 million years ago ruled with more power than any modern species, McGill research into a marine ecosystem from the Cretaceous period revealed. The study, published in the Zoological Journal of the Linnean Society, reconstructs Fossils Capturing a Sea Cow's Violent End Shed Light on Prehistoric Food Chains. New research suggests the dugong-like sea creature was attacked by a crocodile, then its remains were scavenged
The Mesozoic era, which includes the Cretaceous, was marked by rising sea levels and warmer climates, conditions conducive to an explosion of marine biodiversity. The Paja Formation ecosystem was teeming with plesiosaurs, ichthyosaurs, and invertebrates, giving rise to one of the most complex marine food chains in history.

180-Million-Year-Old Fossil Reveals Three Levels of Ancient Food Chain. Exploring Prehistoric Life. Paleontologists. Tuesday, May 18, 2021 the Posidonia Shale offered a rare combination of a shallow to moderately deep continental marine basin, Just how big was the prehistoric super-sized Mosasaurus was at the top of the food chain and would eat pretty much anything they found in the ocean: sharks, cephalopods, giant turtles, and even other mosasaurs. The real Mosasaurus wasn't quite as big as Jurassic World made it out to beโas always, real life fails to live up to the Hollywood hype.
Fossil Hunter Discovers 66-Million-Year-Old Vomit in Denmark, Offering a Clue to the Cretaceous Food Chain. A marine animal snacked on some sea lilies that did not agree with its stomachโand we At the bottom of the food chain were tiny organisms like phytoplankton. These microscopic plants used sunlight to make food, just like plants on land. They were eaten by slightly larger animals called zooplankton. From there, the food web branched out: Small fish ate the plankton; Larger fish and some marine reptiles ate the smaller fish
