New Research Reveals Sick Sea Monsters Swam to Shore to Vomit
- Paleontologist Dirk Knaust identified fossilized vomit in North Sea drill cores, a discovery detailed in Geological Magazine representing the first identification of plesiosaur vomit from the Jurassic Period.
- Like owls, prehistoric plesiosaurs routinely regurgitated indigestible meal leftovers, a behavior Knaust compared to modern fur seals and marine crocodiles to understand the fossil evidence.
- Inside the regurgitalites, Knaust found concentrated remains of shellfish, worm tubes, sea lilies, and hard parts from belemnites, amassing more than 20 such fossilized clumps.
- Plesiosaurs consumed prey in saltier oceans, then traveled to shallow river deltas to vomit, suggesting they sought sheltered coastal waters after feeding episodes.
- This finding provides rare insight into marine reptile evolution during the Jurassic Period, with Knaust stating, "There's so much more we can learn.

Fossilized Vomit Reveals How Plesiosaurs Dined on Jurassic Seafloor
Dr. Dirk Knaust, a geologist with the Norwegian energy company Equinor ASA, has identified plesiosaur regurgitalites -- the technical term for fossilized vomit -- from preserved in rock cores drilled beneath the North Sea, offering a rare window into how these long-necked marine reptiles fed in the Middle and Late Jurassic seas. The post Fossilized Vomit Reveals How Plesiosaurs Dined on Jurassic Seafloor appeared first on Sci.News: Breaking Scie…
Newly discovered fossils suggest giant marine dinosaur came to coastline to vomit
Newly discovered fossils have suggested that a giant marine dinosaur came to the coastline to throw up.Plesiosaurs, the long-necked marine reptiles that patrolled Jurassic oceans, apparently swam towards shallower coastal waters for the specific purpose of vomiting up the indigestible remains of their prey.A study published today in the journal Geological Magazine was based on more than twenty lumps of fossilised vomit recovered from drill cores…
