A new study, by researchers including the Museum's John Ascher, shows that although certain bumble bees are at risk, other bee species in the northeastern United States persisted across a 140-year period despite expanding human populations and changing land use.

By far the largest and oldest group in the order Lepidoptera, moths are usually overshadowed by their flashier cousins, the butterflies. But they are finally getting their due in Winged Tapestries: Moths at Large, a photo exhibition now open at the Museum.

For centuries, humans have been fascinated by giant squids, among the largest—and most elusive—living invertebrate species. The Museum's giant squid (Architeuthis kirkii) specimen is one of few housed in a museum in North America, says Curator Neil H. Landman, who studies fossil (and living) invertebrates in the Division of Paleontology.

Research led by Museum scientists shows that ammonites, an extinct type of shelled mollusk that’s closely related to modern-day nautiluses and squids, made homes in the unique environments surrounding methane seeps in the seaway that once covered America’s Great Plains. The findings, recently published in the journal Geology, provide new insights into the mode of life and habitat of these ancient animals.

In the Black Hills region of South Dakota, researchers are investigating a 74-million-year-old mound of fossilized material where methane-rich fluids once migrated through the sediments onto the sea floor. When the face of this cliff recently slumped off, a wide variety of bivalves, sponges, corals, fish, crinoids, and, as recently documented, ammonites, were revealed.
