In a scene of the recent film Jurassic World, actor Chris Pratt is wrangling a bunch of genetically engineered dinosaurs — as you do — and spreads his arms to take on a crouching, "nope don't even think about it buddy" sort of stance.

And thus a meme was born.

You've probably seen #Prattkeeping on Twitter already: Zookeepers around the world took up the pose with the animals they train, showing that wrangling zebras and giraffes can look just as intense as herding a group of raptors.

And the meme wasn't restricted to zookeepers and animal trainers. People also posed some pretty random inanimate objects, as you can see in the video above. Plus Pratt himself reclaimed the meme by showing off his child-herding skills during a visit to a children's hospital (awwww).

But now the Smithsonian has thrown down the gauntlet, tweeting a picture of a real life dinosaur wrangler — no CGI needed. You might remember Matthew Carrano from a recent post on the blog, where he and the director of NMNH reviewed the movie.

#PrattKeeping may be silly, but it's also one of many examples of how movies in the Jurassic Park franchise have helped scientific progress. Many paleontologists owe their careers to the first film — if not because the movie directly inspired them, then because it sparked an interest in dinosaurs and fossils that allowed museums to put paleontologists on staff.
