Djupedalia was a long-necked marine reptile that swam in the warm, shallow seas near Svalbard, Norway, about 150 million years ago. It was not a dinosaur, but a plesiosaur, a type of ocean predator. With its small head and long neck, it likely snapped up fish and squid while paddling through the water.4 2

Inyani emnandi: esi sirhubuluzi saselwandle sasiqubha ngelixa iidayinaso zazihamba emhlabeni. Wonke umntu uzibiza ngokuba ziidayinaso, kodwa zazilisebe elahlukileyo lezirhubuluzi.

izinto ezimnandi

Iinyani ezimnandi

Djupedalia is known from a single juvenile skeleton that is one of the most complete marine reptile fossils ever found in Spitsbergen.2

Its neck bones were special: the neural spines (the parts that stick up from the vertebrae) were shifted far back, and the postzygapophyses (the joints that connect vertebrae) were very long.2

Djupedalia had femora (thigh bones) that were longer than its humeri (upper arm bones), which is unusual for plesiosaurs.2

The fossil was found about 20 metres below a rock layer called the Dorsoplanites bed, which is full of ammonite shells.2

Djupedalia lived during the Tithonian age, about 150 to 145 million years ago, in the Late Jurassic period.1

Umfanekiso owenziwe yi-AI: Djupedalia — Umfanekiso owenziwe yi-AI obonisa indlela Djupedalia esenokuba wayekhangeleka ngayo, wenziwe yikhompyutha ngokwento eyaziwa zizazinzulu. Kukuqikelela nje: esona silwanyana sinokuba sasikhangeleka ngenye indlela, kwaye akukho mntu waziyo imibala yaso yokwenyani.

Inyaniso ngeentsomi

Intsomi: Some people might think Djupedalia was a dinosaur because it lived in the sea and had a long neck.

Inyaniso: Djupedalia was a plesiosaur, a marine reptile, not a dinosaur. Dinosaurs lived on land, while plesiosaurs swam in the ocean.4

Kwiingcali zeedayinaso

Igama lenzululwazi: Djupedalia
Inikwe igama ngu:: Knutsen et al. 20124
Iqela: Iiplesiosauri
Usapho / iclade: Cryptoclididae4
Ukuhlelwa: Plesiosauria > Sauropterygia4
Ubudala bamatye: 149 ukuya ku-143 izigidi zeminyaka (Tithonian)4
Izakhiwo zamatye: Agardhfjellet4
Amazwe: iNorway4
Iirekhodi zeefosili: 1 kwi-Paleobiology Database4
Ukufunyanwa: Djupedalia was named in 2012 by Espen M. Knutsen, Patrick S. Druckenmiller, and Jørn H. Hurum. The fossil was excavated in the summer of 2009 by the University of Oslo Natural History Museum from the Slottsmøya Member near Janusfjellet mountain.2
Kusaxoxwa ngayo: Scientists are still debating exactly how Djupedalia is related to other plesiosaurs, since it shares features with several different groups from England and other places.2
