Here is the Kyhytysuka sachicarum!


The fossilized bones include a remarkably preserved one-meter-long skull. They belong to one of the last ichthyosaurs that lived 130 million years ago.

The species named ” Kyhytysuka sachicarum »Bears a strong resemblance to current swordfish and brings a new light on the evolution of the last hypercarnivores.

This is an animal that has developed teeth adapted to the predation of large animals., explains in a press release Hans Larsson, director of the Redpath Museum.

The other ichthyosaur species discovered so far have jaws with small, regular teeth adapted to predation by small animals.

The size and distribution of this saurian’s teeth have evolved to make its jaw a formidable weapon for capturing large prey, such as large fish or other marine reptiles., notes Mr. Larsson.

The ichthyosaurs, which hunted in deep waters, the short-necked plesiosaurs and sea crocodiles that populated the many marine ecosystems of the Jurassic period are giving way to new generations of long-necked plesiosaurs, sea turtles, large lizards called mosasaurs and to our giant ichthyosaur, adds Ms. Cortès.

The Colombian region where the fossil was discovered was a hotbed of biodiversity. Kyhytysuka“,” text “:” We are still discovering many other species in the rocks of the area where we found the ichthyosaur Kyhytysuka “}} ‘>We are still discovering many other species in the rocks of the area where we found the ichthyosaur Kyhytysuka, rejoices Dirley Cortès.

One of paleontologist Dirley Cortès’ next goals is to explore the multitude of new fossils that regularly arrive at the Paleontological Research Center in Villa de Leyva, Colombia. This is where I grew up, and it is extremely rewarding to conduct my research there., specifies Dirley Cortès.

The detail of this discovery is described in the Journal of Systematic Palaeontology (New window) (in English).
