door 19

Knock 3.14159 times on Door 19 for admission to an oddly charming evening that will forever change how you think about science. Curated for the curious, Door 19 is quirky science meets themed soiree, set against a backdrop of live performances, music, potent libations, and dinosaurs.

For only three nights this year, you will have the chance to go beyond the galleries and into specimen collections off-limits to visitors, alongside experts who will bring our coolest specimens out to play. Our rogue scientists will go a little bit off script to share their most incredible knowledge—from creepy taxidermy to medicinal botanicals. You’ll be reminded that no, in fact, you haven’t seen it all—far from it.

Door 19: Sippin’ With Sloths (SOLD OUT)
Thursday, February 27, 2020, 6–9 p.m.

Slam the brakes, slow your roll and slide on over to the Academy: real sloths are coming for an adults-only cocktail party.
Sloths are trendy and tre cool, and for good reason — any animal that is so relaxed that algae grows on its back is pretty much the coolest creature in the trees. At “Door 19: Sipping with Sloths,” explore the unexpected adaptations that give living things (like sloths) an edge, from slowness to senescence. Take a rare chance to scope out the million specimens in our largest collection, or pull out some drawers to study skins behind the scenes. Learn what the “slow food movement” really means, take action by getting some with conservation condoms and cheer on your favorite competitor in the tortoise and the hare race. Dress to impress (sloths are very distinguished!) or come as you are for an offbeat evening with live music, fabulous food and an open bar.

  • Find yourself face to fur with LIVE two-toed sloths
  • See the strangest slides from the Diatom Herbarium or the weirdest specimens in the Mammalogy Collection
  • Bring your dancing shoes to cut a rug with live music
  • Discover who is really faster, the tortoise or the hare
  • Taste slow food with Slow Food Philly and find out what happens when you digest the best that nature has to offer
  • Learn how being the fastest might slow you down or how being the biggest has the smallest payoff
  • Get romantic with the crafty conservationists from Endangered Species Condoms
  • Snack on savory and sweet treats from our exclusive caterer, 12th Street Catering (vegetarian options available)
  • And … did we mention the open bar?

Drawn to Dinosaurs

Drawn to Dinosaurs delves into the science and art of visualizing a living animal based on fragmentary fossils. This intimate exhibit illustrates what scientists can deduce from the fossil record when creating a reconstruction of a skeleton or model and what they must look to artists to interpret. The centerpiece is a full cast of the plant-eating dinosaur Hadrosaurus foulkii, discovered in 1858 in Haddonfield, NJ. The Academy created a full cast of this duck-billed dinosaur and put it on display in 1868, becoming the first place in the world where the public could go to see a dinosaur. Now it’s back.

The current life-size drawing of Hadrosaurus is done by paleo-artist Christopher DiPiazza, who created his drawing during our February Paleopalooza event. See it today!

Dinosaur Hall

Dinosaur Hall

It’s one of the first things visitors see when they enter the Academy of Natural Sciences: measuring up to 42 feet in length and weighing in at an estimated 7.5 tons, Tyrannosaurus rex was one of the largest predators to ever walk the Earth. This impressive animal is one of many dinosaurs and other Mesozoic creatures you’ll encounter in Dinosaur Hall. More than 30 species are represented, about half of which are full skeletal mounts, including Avaceratops, Chasmosaurus, Corythosaurus, Deinonychus, Pachycephalosaurus, Tenontosaurus, and Tylosaurus.
