This monster appears in the artwork of "Jurrac Impact". In fact, the said card is similar to this card's effect.
This card's name doesn't come from a dinosaur, and it is the only "Jurrac", besides "Jurrac Ptera", that is not based off a dinosaur (though it may be based off of the meteor that was believed to have caused the dinosaurs' extinction, which explains the first part of its effect).
The fact that this card is a dinosaur based off of a meteor is likely intended for irony. The idea given by the form and effect suggests that a dinosaur may have killed the other dinosaurs.
This monster bears a striking resemblance to "Lavos", the main antagonist from the video game Chrono Trigger (its shell in particular is near-identical to that of "Lavos"). Interestingly, in the game, "Lavos" is the meteor that caused the extinction of the dinosaurs.
