ARGENTINA-CHILE-DINOSAUR-CHILESAURUS DIEGOSUAREZI

Paleontologist Marcelo Isasi, shows to his sons a replica of a Chilesaurus diegosuarezi, a bizarre genus of herbivorous theropod dinosaur, is exhibited at the Bernardino Rivadavia Natural Sciences Museum in Buenos Aires, Argentina, on June 23, 2015. The bizarre creature was named after the South American country where its fossilised remains were found, and the seven-year old boy, Diego Suarez, who discovered the first bones in 2004 while exploring the Andes mountains with his geologist parents. Chilesaurus diegosuarezi had a bird-like beak with leaf-shaped teeth, evidence that it feasted on plants, but with hind leg features similar to theropod dinosaurs, the group into which it was slotted with notorious killers like TyrannosaurusRex, Velociraptor and the horned Carnotaurus.
