Let's make this birthday one to remember.

78 years old (Born on June 15, 1946)

Happy Birthday, Jack Horner! From digging up Maiasaura nests and proving dinosaurs were caring parents (who knew T-Rex had a soft side?), to making sure Jurassic Park didn't accidentally give velociraptors feathers too soon—your contributions have been dino-mite!

Thanks for keeping Hollywood scientifically accurate—or at least as close as Spielberg would allow. Your discoveries continue inspiring generations of paleontologists and dinosaur enthusiasts alike. May your birthday be filled with laughter, fossils, and absolutely no rampaging dinos escaping from theme parks.

Here's hoping this year brings you even more groundbreaking finds—and fewer angry raptor calls from movie directors!
