a Triceratops with Thagomizers

[MaastrichtianGuy]

so i know u guys heard that some illustrations of the dimetrodon had tall skinny jagged spikes on its back rather than having a sail on its back but what u probably do you hear of that triceratops in real life dont have thagomizers since stegosaurs are the only ones to have thagomizers but what u have heard  that theyre are some or few illustrations that the triceratops is incorrectly having thagomizers on the end of its tail but havent seen an episode of the fairly oddparents named movie magic and theres this scene which is the cretaceous era which has a bat winged pteranodon in the beginning of the scene and to the middle of the scene with the t-rex they have a triceratops sporting or having thagomizers in the end of its tail as you seen in the right side of the scene. so can anyone know whats this thagomizer tailed triceratops is based on?

It might me a misinterpretation of quills. Or the Stegoceratops, which is actually a rather old concept. Probably the latter, given the rather outdated look of the Tyrannosaurus. Maybe that world is just weird. Normally 10 year olds aren't the size of soccer balls, aren't they?

I just think the creators just had no knowledge of dinosaurs.

Triceratops with thagomizers goes back a long way in cartoons and cheap plastic toys, kinda like rhamphorhynchus-tailed toothed Pteranodon. It's just about toy makers or animators picking and choosing the coolest bits of various dinosaurs and not knowing or caring which features are exclusive to which species.
