Author Joyce Carol Oates retweeted a photo of Steven Spielberg with a message critical of him for “killing” a triceratops.

One surefire way to upset the online public is to post photographs of big game hunters and their trophy kills, especially when those kills involve animals that are endangered (or perceived as such). Typically, this outrage involves animals such as a giraffes or elephants and hunters whose identities are unfamiliar to the general public.

According to author Joyce Carol Oates’ tweets, however, she is apparently upset with director Steven Spielberg for killing an animal that has been extinct for millions of years, a triceratops:
