Today, , an ABC TV program following a family of dinosaurs realized through elaborate animatronics, isn’t super well-known, especially by younger viewers. The exploits of Earl and Fran Sinclair and their wacky family certainly haven’t had the pop culture longevity ofThe Simpsons or Bob’s Burgers. However, in its time, this production (which was developed by Jim Henson) ran a respectable four-season run that included 65 episodes. These installments touched on a variety of heady topics (like political scandals and drug use) that helped to accentuate the program’s all-ages appeal.

Dinosaurs certainly wasn’t afraid to get challenging, as seen by episodes like “The Greatest Story Ever Sold” or “The Last Temptation of Ethyl” which skewered organized religion. Still, even longtime fans aware that Dinosaurs had a willingness to go provocative places could’ve never imagined where the program’s finale was heading. The last Dinosaurs episode was “Changing Natures,” and it’s become infamous for even traumatizing adults who watched ts original airing.
