Trophy-Girl & The last of its kind

A Hobby huntress encounters a primeval species thought to be extinct in South America. The young dinosaur knew nothing of humans. It was unsuspecting, curious and hungry. It could be lured with chocolate bars, petted, and fed by hand.
It looked friendly and attentive as the young huntress swung her machete wide. The steel glinted briefly in the sunlight. She carried the trophy over her shoulder to the nearest hunting camp. The head was too big and too bloody for her expensive designer backpack. When she was arrested, she was asked if she was ashamed of what she had done. Her answer: She, or someone else, probably the last of its kind, wanted to spare it the expected media frenzy and death in the zoo.
Death came quickly and painlessly, with a grateful look on her face.
