A photo of a fossilized trilobite. It is brown in color and somewhat resembles a horseshoe crab.
It's Trilobite Tuesday! Proetid trilobites survived in the world's seas for almost 200 million years, beginning in the early stages of the Ordovician & lasting until the end of the Permian Period. The specimen pictured—the proetid Warburgella—comes from Malvern, England's Silurian Period exposures.

A photo of a Taiwanese serow facing the viewer. It is illuminated by strong sunlight. It has brown fur and small horns.
Behold the Taiwanese serow! Of the four living members of the genus Capricornis, this species is the smallest—reaching weights of only 60 lbs (30 kg). It inhabits mountainous forests on the island of Taiwan.

A photo of the head of pachycephalosaurus visible in profile. The animal has a beak-like mouth and a domed head.
This Fossil Friday, meet Pachycephalosaurus! It was once theorized that, like modern bighorn sheep, it used its skull as a battering ram. More recent studies have challenged this idea, suggesting Pachycephalosaurus may have knocked its opponents’ sides like modern day bison.

A photo of a Vancouver Island marmot sitting on a rock. The animal is chocolate brown in color with a pale snout and pale markings on its chest.
The Vancouver Island marmot is one of North America’s rarest mammals. By the early 2000s, fewer than 30 individuals remained. Since then, conservation efforts have bolstered its numbers to more than 400—however, it remains critically endangered.

I was back at the @amnh.org for a new SciCafe talk. This was about the weakening of the Gulf Stream & climate change. The speaker, an oceanographer, talked how a new analysis changed his position on the subject which highlighted the self-correcting nature of science. Yay science! lol. #AMNH

A photo of a spectacled bear approaching the viewer. The animal is stocky with black fur. Its face is marked with gold, the pattern of which somewhat resembles a pair of spectacles.
Meet the spectacled bear! Also known as the Andean bear, it’s distinguished by the glasses-shaped marking on its face. An inhabitant of the tropical Andes, it’s currently the only extant bear species in South America.

A photo of a Bornean pig. The pig is covered in brown hair and has a bushy, wiry beard.
Meet the Bornean bearded pig! This whiskered swine inhabits rainforests & mangroves in parts of Southeast Asia. It sometimes gathers in groups of 100+ individuals to migrate in search of fruit. It has the leanest torso & longest head of all living pigs.

Modular reorganization of the trilobite Lonchodomas chaziensis demonstrates mosaic patterns of phenotypic change underlie metamorphosis
Abstract. Some trilobites underwent drastic morphological transformations through their development. The Ordovician trilobite Lonchodomas chaziensis transf
A recent study, led by Museum Research Associate Ernesto Vargas-Parra and Museum Curator Melanie Hopkins, suggests that trilobite heads were made of semi-independent modules and the number of modules decreased over metamorphosis—similar to butterflies or beetles! Read more about the findings.👇

It's Trilobite Tuesday—and we have new research to share! On the left is a 3D scan of Lonchodomas chaziensis babies that are about the size of a grain of sand. The accompanying photo on the right shows an adult specimen of the closely related species Lonchodomas rostratus.

If the weather is clear, sky watchers in North America, Australia, and East Asia will have a view of a total eclipse of the Moon. Cloud cover and other atmospheric conditions may also affect the visibility and coloration of the Moon. The next total lunar eclipse won’t happen until June 26, 2029.

Image of the moon in the night sky. It appears reddish in color.
Blood Moon alert! Totality—when the Moon is fully immersed in Earth's dark umbral shadow & appears blood-red—will begin at 6:04 am ET on 3/3 in NYC & peak at 6:33 am ET. Totality will last for ~58 minutes, after which the Moon will begin to exit from Earth's shadow.

A photo of a Malayan tapir looking at the viewer. The animal is black and white in color. It has a drooping proboscis.
Meet the Malayan tapir. This critter's unique nose (proboscis) helps it breathe while in water. Though it may be friend-shaped, give it space: It weighs ~1,000 lbs (450 kg) & can run faster than an Olympic sprinter!

A photo of a swimming platypus. It is covered in brown fur and has a black, duck-like bill.
With a duck-like bill, beaver-like tail, and the ability to lay eggs, the platypus has a lot going on. It lives in Australia, where it inhabits fresh water. It also happens to be venomous, inducing excruciating pain with its sting.

A close up photo of a sand cat peering at the viewer with narrowed eyes. Its coat is golden in color.
Meet the sand cat. Thick soles on its paws allow it to withstand the temperature extremes of desert sand. In parts of its range, days can reach 124° Fahrenheit (51° C) and then plummet to 31° Fahrenheit (-0.5° C) by night!

It’s a bird! It’s a plane! It’s… a dinosaur? Nope to all of the above. This #FossilFriday, let’s celebrate pterosaurs, flying reptiles that ruled the skies for 150+ million years. Some were as small as paper airplanes while others had wingspans bigger than an F-16 fighter jet!

A photo of a red panda curled up in a relaxed pose. Its fur is auburn, though darker at the belly and with white markings on its face. It somewhat resembles a lean raccoon.
Despite resembling the raccoon, the red panda is in its own distinct family: Ailuridae. Spending most of its life in the treetops, it uses its long tail as a counterbalance & can rotate its feet 180 degrees to aid it in gripping tree bark & branches.

This serves as an example of evidence of plate tectonics, which explains how continents move ever-so-slowly over the course of hundreds-of-millions of years.

Two photos of two different trilobites. One is tannish in color, the other is dark. Both have long spiny appendages.
t’s Trilobite Tuesday! Pictured above is a Ceratonurus trilobite from Oklahoma. Strikingly similar examples of this genus have been found some 4,970 mi (8,000 km) away in Morocco, such as the one pictured below.

Caturday Mood? Pallas' cat. Found in parts of Asia, it lives a primarily solitary life & only seeks out company during mating season. A female Pallas’ cat produces a litter of one to six kittens, and by just 5 months old, they disperse to set out on their own!

A photo of the fossilized remains of Deinonychus mounted in a leaping position. The animal has a long tail, sharp teeth, and a slender body.
It's Fossil Friday! Meet Deinonychus antirrhopus. It belonged to a group of dinosaurs called maniraptors, or “hand-robbers.” Its hands & feet were equipped with sharp claws for catching & grasping prey. With its sickle claws & sharp teeth, it was likely a fierce predator.
