"150-Year-Old Mystery Solved: Giant Ichthyosaur Bones Identified"

A study from the University of Bonn suggests that large, fossilized bone fragments found in Europe since the 19th century may have belonged to gigantic ichthyosaurs, marine creatures that could reach 25 to 30 meters in length. The microstructure of the fossils indicates that they come from the lower jaw of these ancient sea creatures, refuting previous claims that the bones belonged to land-living dinosaurs. The unusual structure of their bone walls, similar to carbon fiber-reinforced materials, likely allowed for fast growth and stability, and the findings have been published in the journal PeerJ.
