Prehistoric puke reveals hunting (and hurling) habits of ancient ocean predators
Prehistoric puke may not sound appealing, but for paleontologist Jesper Milan, it offers a fascinating glimpse into the hunting habits of ancient ocean predators. Recently discovered by a private fossil hunter on a coastal cliff in Denmark, this 66-million-year-old vomit contains the preserved remains of two crinoids, also known as sea lilies.
When Milan first saw the fossil, he didn’t realize its significance. But as museum staff cleaned it up, they uncovered the skeletal remains of the sea lilies coiled together in a pellet, leading them to believe it was vomit. This regurgitalite, as it is scientifically known, provides valuable insights into ancient ecosystems and the diet of marine creatures during the Cretaceous period.
Russell Bicknell, a paleobiologist at the American Museum of Natural History, explains that fossilized vomit is rare but essential for understanding prehistoric food chains. The sea lilies’ calcite skeletons were well-preserved in the regurgitalite, shedding light on what type of predator may have consumed them.
While the exact identity of the creature that produced the vomit remains unknown, Milan speculates that a bottom-dwelling shark, such as the Port Jackson Shark, could be the culprit. These sharks feed on hard-shelled marine organisms, making them a likely candidate for regurgitating the sea lilies.
Milan is thankful for the attention this discovery has garnered and acknowledges the contribution of amateur fossil hunters like Peter Bennicke, who found the prehistoric puke. In Denmark, a significant portion of fossils come from these enthusiasts, highlighting the importance of their work in uncovering the secrets of the past.
Overall, this ancient vomit provides a unique window into the hunting and feeding behaviors of ancient ocean predators, offering valuable insights into the prehistoric world. It serves as a reminder of the importance of preserving and studying fossils to unravel the mysteries of our planet’s history.
