“Frozen behaviors” in amber fossils – how to reconstruct mating behavior of long-extinct termites

Researchers from OIST used X-ray micro-CT to study a 38 million-year-old termite pair trapped in amber, revealing a male and female in tandem running behavior. The discovery provides new insights into the fidelity of behavior fossilization in amber.

Why do we find so much amber in Cretaceous rocks?

Researchers discovered that coniferous forests spread across the planet during the Cretaceous period, allowing for high resin production and creating conditions suitable for mass formation of amber deposits. The study sheds new light on Earth's history, revealing insights into ancient ecosystems dominated by flowering plants.

Natural History Museums of Los Angeles County’s Dr. Luis Chiappe co-authors paper on relationship between feathered dinosaurs and beetles

Researchers from Natural History Museums of Los Angeles County have discovered evidence of a symbiotic relationship between Cretaceous dinosaurs and feather-feeding beetles. The study found that the beetles fed on the feathers of theropod dinosaurs during the Early Cretaceous period, approximately 105 million years ago.

Entombed together: Rare fossil flower and parasitic wasp make for amber artwork

A rare fossil flower of the Euphorbiaceae family has been discovered in 30-million-year-old amber, along with a parasitic wasp. The flower, named Plukenetia minima, is notable for its small size and lengthy stalk. The wasp, Hambletonia dominicana, was found to have an egg that hatches into a fly larva within the flower's seed pods.

Amber fossil reveals new clues about ancient cockroach ecology

A 100-million-year-old cockroach fossil provides insights into its sensory organs, which suggest the species lived in bright environments during the day. The study found that the extinct species had well-developed eyes and a unique pattern of receptors on its antenna, indicating it may have used these to communicate between sexes.

International team of researchers discover first dinosaur era crab fully preserved in amber

A team of scientists has discovered the oldest modern-looking crab, Cretapsara athanata, preserved in 100-million-year-old amber. The fossil is remarkably complete, including delicate tissues and well-developed gills, revealing an aquatic to semi-aquatic animal that defies explanation for its preservation in tree resin.

Scientists reconstruct beetles from the Cretaceous

A research team led by the University of Bonn has reconstructed four newly found beetle species using computer tomography, providing insights into their morphology and evolutionary history. The study suggests that beetles suffered a decrease in diversity during the Cretaceous period as plants transitioned from gymnosperms to angiosperms.
