Museum collections are invaluable scientific and听education听tools that celebrate the past, define the present and inform the future. Embedded in our cupboards, shelves and freezers is hidden information waiting to be teased out by current and future scientists. Our collections provide opportunities and access for CU students to gain real world experience in preparation for careers essential for solving the challenges of tomorrow.听

In the spring of 2020, like many organizations around the world, the CU Museum of Natural History Boulder was forced to close its doors due to COVID-19.听Each and every听week, for over a year, the museum highlighted the history of a single听catalogued听item from our vast collection of more than 5 million objects. Each听Wonder of the Week, or听WoW听blog posted on a Wednesday鈥攐ffered something interesting and new to anticipate. To view the collection through a post-lockdown lens, explore the following posts.

Coprolites

Feb. 3, 2021

Can you guess what kind of fossil this is? Hint: the light-colored fragments in the specimens are many pieces of chopped-up bone. Although this may not look like much, careful study by CU scientists who examined the fragmented bone contents, chemical composition, and geological context of the specimen, it was concluded that the only way that this mineralized bone-filled mass could have formed in the ancient environment was through the fossilization of carnivore feces. AKA coprolites鈥攖his one was likely produced by a large carnivorous dinosaur around 140 million years ago.

Bryozoan

Jan. 13, 2021

Each hole you see in this image at one point housed a miniature animal. Together, these tiny animals created a netlike colony: the bryozoan. While this image displays an encrusted fossil from the Pleistocene (2.58 million to 11.7 thousand years ago), there are many bryozoan varieties alive today, their habitats ranging from the shallow reefs of the tropics to the frigid waters of the poles.

Disco Clams

Jan. 6, 2021

This saltwater bivalve goes by quite a few names including 鈥渆lectro-flame scallop,鈥� 鈥渆lectric clam,鈥� and 鈥渄isco clam鈥� and it鈥檚 easy to see why. These animals are vibrantly colored and are among only a couple bivalves that can display a light show. Disco clams light up鈥攆lashing 鈥渓ights鈥� along their red mantle to confuse and deter predators.

Pi帽on Pine

Dec. 23, 2020

Pi帽on Pine (Pinus edulis) is a relatively small tree found on dry slopes and mesas at lower elevations (4,500-9,000鈥�) of southwestern North America. In baby直播app, this pine most often populates the canyon country of the Western Slope and in the oak-shrub zone of the southern mountains and plains. Amazingly, this tree can live up to 1,000 years, making it a fixture in high desert landscapes.

Braiding Sweetgrass

Dec. 16, 2020

Sweetgrass is a perennial grass with hollow stems and underground rhizomes. It has a purple, red, and white hairless base and can grow to about 30 inches tall. Sweetgrass flowers early for a grass鈥攆rom May to July. The pressed specimen here was collected in July at the end of the bloom when the flowers were drying.

European Mantis

Dec. 9, 2020

Of the seven species of mantises in baby直播app, Mantis religiosa, is one of the largest and most common. They measure up to three inches long and range in color from tan to a bright green, which helps them camouflage from predators. These insects are most recognizable by their triangular-shaped head and 鈥減ious鈥� posture with their raptorial first set of arms. At rest, this species will sit, with their front arms folded making it appear as though they are praying, earning their species name religiosa.

Brittle Star

Nov. 25, 2020

Ophiodia peloria, commonly known as Brittle Star are omnivorous, scavengers and detrivores, (meaning they eat dead and decaying things off the sea floor). Their mouth, which is located on the bottom side of their disc-shaped body is used to both ingest food and expel waste products. These animals eat by pushing their stomachs out of their mouth, pressing it against the food source, then retracting it with its contents back into the body.鈥疘n short, the one opening acts as mouth and anus.
