The 'Holy Shit It's a Dinosaur' meme originates from the 1993 cinematic masterpiece Jurassic Park, specifically the scene where Dr. Alan Grant and Dr. Ellie Sattler witness a Brachiosaurus for the first time. While the original movie scene is one of pure cinematic awe, the meme took a comedic turn in the late 2000s and early 2010s with the rise of YouTube parodies. A particularly famous version features a comedic lyrical interpretation of John Williams' iconic score, turning the majestic moment into a profane exclamation of disbelief. Today, the template is used to react to anything shockingly large, unexpected, or impressive, blending 90s nostalgia with internet-era absurdity.
