Scientists find first-of-its-kind small armoured dinosaur size of pet cat
Jakapil kaniukura may have had a two-legged stance unlike most armoured dinosaurs of this kind, 科学家说

Paleontologists have unearthed a first-of-its kind small armoured 恐龙 in southern 阿根廷 that likely weighed as much as a pet cat and walked upright on its back legs.

The dinosaur, 命名 Jakapil kaniukura, lived about 100 million years ago during the Cretaceous Period and had rows of disk-shaped bony armor along its neck and back down to its tail, 研究人员说.

The unearthed “subadult” dinosaur was estimated to have been “less than 1.5m in body length and to have weighed 4.5–7 kg”, said scientists, including those from Universidad Maimónides in Argentina, in a study published in Scientific Reports 星期四.
