About

Key-Points

• Kyhytysuka means “the one that cuts with something sharp”. The word belongs to the indigenous language of central Columbia.
• The new species has been named Kyhytysuka sachicarum to honour the Muisca culture of central Columbia. 
• The Muisca is also called Chibcha. They were conquered by the Spanish in 1537. They were mainly agrarians. They also extracted salt from the sea.
• The fossil is a stunningly preserved meter-long skull, is one of the last surviving ichthyosaurs – ancient animals that look eerily like living swordfish.
• Ichthyosaur-
• They are the members of an extinct group of aquatic reptiles, most of which were very similar to porpoises in appearance and habits.
• They had a very wide geographic distribution, and their fossil remains span almost the entire Mesozoic Era.
• They are first known from the Triassic Period of Asia, where they began as long-bodied, undulating swimmers without many of the specializations seen in later species.

Features of Kyhytysuka

• It was a mid – sized ophthalmosaurian. The Ophthalmosaurus belonged to the Jurassic period.
• It had extremely large sized eyes, dolphin – shaped body.
• The jaws had many robust teeth.
• It had several adaptations.
• It was a macro predatory vertebrate hunter, which means it hunted larger vertebrates. Vertebrates are organisms with backbone. Organisms without backbone are called invertebrates.
• The species was mostly found in shallow waters.
• The dentary is the longest bone of the species. It measures 720 mm. 
• The dentition is the most unique feature of the species. 
• The teeth are seated in continuous grooves. The teeth are slightly curved posteriorly. Also, an alternating wave – like pattern is observed.
