  • You know how sometimes you're just sitting around wondering what dinosaur meat might

  • have tasted like?

  • Well chances are you might have eaten dinosaur meat recently

  • Technically, birds are dinosaurs.

  • If you look at bird skeletons, they look remarkably similar to dinos.

  • And over the centuries, paleontologists have found lots of fossilsfrom Archaeopteryx

  • to Ornithomimusthat suggest modern birds are direct descendants of dinosaurs.

  • Because biologists classify things based on relatedness, that makes pigeons, falcons,

  • and every other modern bird a living dinosaur.

  • So that chicken pot pie you had last night, or those game day buffalo wingsthat's

  • all delectable dino.

  • In fact, you could say that dinosaur is actually the most popular meat in America.

  • Of course, when most people think of dinosaurs, they mean the extinct, non-avian kind.

  • So would those dinosaurs have tasted like chicken?

  • Well, even among birds today, there's quite a range of flavors: chicken is different from

  • turkey; turkey is different from duck

  • There's even emu.

  • A lot of different factors could have affected the flavor of dino meat.

  • Meat, after all, is muscle, and muscle fiber comes in two varieties.

  • Slow-twitch fibers are what we know as red or dark meat.

  • They're used for lower-intensity, longer-duration activities like walking around.

  • The dark color comes from a protein called myoglobin, which binds iron and supplies oxygen

  • to these constantly hungry muscles.

  • Fast-twitch fibers, on the other hand, make up white meat, and are used for occasional

  • bursts of intense activitylike a chicken using its breast muscles to flap its wings.

  • Because these fibers really only need energy every now and then, they rely on glycogen,

  • a stored form of sugar, and don't have as much myoglobin, so they look white.

  • Fast-twitch muscle isn't worked out as much, so it's more tender, but it has less flavor.

  • Dinosaurs would have different amounts of white and dark meat depending on their lifestyles.

  • An herbivore like Brachiosaurus that was constantly on the move in search of food might be heavy

  • on the dark meat, while a predator that specialized in sudden bursts of movement like a velociraptor

  • would have more white meat.

  • What an animal eats also has a big effect on how it tastesthink of the difference

  • between a burger made from grass-fed cows and one made from cows raised on grain.

  • There were a few grain-eating dinosaurs, and lots of others dined on plants, so you would

  • have had your pick.

  • Back in the Mesozoic, dinosaurs were usually the ones chomping down on mammals, but you

  • would have a least one fellow dino-diner.

  • In 2005, researchers discovered a fossil of an opossum-sized mammal that had the remains

  • of a baby dinosaur in its gut.

  • So, even if we can't pinpoint the exact flavor profile of dinosaur meat now, rest

  • easy knowing that your ancestors had a pretty good idea.
