Borealonectes is one of the few plesiosaurs known from the Jurassic of North America.1

It was the first marine reptile from the Canadian Arctic with a well-preserved skull.1 2

The only known fossil includes a skull, neck vertebrae, and the right forelimb.1

Borealonectes lived during the Middle Jurassic, about 165 to 161 million years ago.1 3

It belonged to a group called rhomaleosaurids, which were short-necked plesiosaurs.1 2

The name Borealonectes means 'northern swimmer' in Greek.1

Chithunzi cha Borealonectes chopangidwa ndi AI — Chithunzi cha momwe Borealonectes mwina ankaonekera, chopangidwa ndi kompyuta kuchokera pa zomwe asayansi amadziwa. Ndi kungoyerekeza: nyama yeniyeniyo mwina inkaoneka mosiyana, ndipo palibe amene akudziwa mitundu yake yeniyeni.

Kupezeka: Borealonectes was named in 2008 by Tamaki Sato and Xiao-Chun Wu based on a partial skeleton found in the Hiccles Cove Formation on Melville Island, Canada.1 2
Akukambiranabe: Scientists are not sure exactly how big Borealonectes grew, because only one partial skeleton has been found.1

Mfundo iliyonse patsamba lino ili ndi nambala yosonyeza kumene yachokera. Ngati talakwitsa kanthu, pepa, ndife okonda madino, osati magazini ya sayansi. Tiuze pa [email protected] ndipo tikonza.
