Leaping Laelaps! That was the first title of this famous Throwback Thursday watercolor by Charles R. Knight. Knight’s late 19th-century painting was unique at the time for its depiction of dinosaurs as highly active and dynamic animals. #AMNH150 (1/3)
What ungulate has a chestnut coat with white stripes, heavy spiraled horns, and lives in Africa? Meet the bongo! This mostly nocturnal animal has large ears and an excellent sense of hearing, which helps it to detect and evade threats that go bump in the night. [📸: JMSchneid]
Say “hi” to Klaas’s Cuckoo! Like other species of cuckoos, it exhibits a behavior known as brood parasitism: females lay their eggs in other birds’ nests & fly away, leaving other parents-to-be responsible for incubating & caring for their hatchling. [📸: Derek Keats]
Not everyone can pull off bold brows like the Spot-bellied Eagle-owl! These “brows” are actually ear tufts that grow ~3 in (7.6 cm) long! Big brows and stature—lengths of ~25 in (65 cm) with a wingspan of ~18.8 in (47.8 cm)—add up to an imposing look. [📸: N A Nazeer]🦉
“I can haz rodents, rabbits, and birds?" That's what's on the menu for the European wild cat! Besides geographic range, what sets the European sort apart from the African wild cat & the Asiatic wild cat is its bushy tail, thick fur, & overall bulkier appearance. [📸: Emőke Dénes]
Happy #FossilFriday ! Does the end of the week have you feeling like this Polyglyphanodon sternbergi? Polyglyphanodon was a large lizard that lived some 85 million years ago. Judging from its unusual chiseled teeth, it had a specialized diet, but what it ate is unknown.🦎🦴🔍
If you ever find a pseudoscorpion in your house, don't worry! The tiny 2-8 mm- (.08-.31 in-) arachnid is harmless to humans. It's sometimes found in sinks & bathtubs, but it's also known as a “book scorpion” because some species have an affinity for old books! [📸: N.Roman]📚🦂
The external, private event at which the current President of Brazil is to be honored was booked at the Museum before the honoree was secured. We are deeply concerned, and we are exploring our options.
Next time you eat guacamole, thank a giant ground sloth: the Lestodon! These 15-ft animals ate avocado whole, traveled, and then pooped, depositing the pits in new places. Most mammals couldn't handle large seeds, so it was up to megafauna to disperse (and fertilize!) avocados.
Today is the winter solstice, the shortest day of the year in the Northern Hemisphere & the first day of winter! What causes our planet’s shift in seasons? Its tilt. Today, Earth’s Northern Hemisphere is at its most-tilted away from the Sun. [📸: Jon Bunting]

A Suriname toad mother carries her young embedded in the skin of her back. After mating, the eggs sink gradually into the female's back, & a skin pad forms over the eggs. The froglets emerge over a period of days, thrusting their head & forelegs out first, then struggling free.
Behold the rainbow eucalyptus! What gives it such a spectrum of color? Bark starts out in shades of green, but changes to a range of purple, red, & orange as it peels and ages. Variety of color may help the tree absorb a wider range of light to aid in photosynthesis.
Discovered in 2012 on Madagascar, Brookesia micra is one of the smallest reptiles in the world! An adult grows to be just over 1 in (2.5 cm) long, and a juvenile can fit on the head of a match (as pictured). [📸: Frank Glaw, Jörn Köhler, Ted M. Townsend, Miguel Vences | PLoS ONE]
