Labandeira, from the Smithsonian National Museum of Natural History in Washington (United States); Eduardo Barrón, from the Geological and Mining Institute of Spain (IGME); Jes Rust, from the University of Bonn, and Bo Wang, from the Nanjing Institute of Geology and Paleontology (China). Fossil amber, a window to the past Amber is a resin fossilized millions of years ago capable of preserving fossil organisms while

maintaining their morphological and structural characteristics with great fidelity. In some cases, amber also provides information on aspects of the behavior of extinct species. The Burmese amber pieces in the new study correspond to the Cenomanian period, when dinosaurs were scattered across all continents. Experts have Uganda Phone Number List  identified several specimens of beetles in three pieces, while a fourth there is only a single specimen. At present, all this fossil material discovered in Southeast Asia is deposited in the Museum of Natural Sciences of Barcelona (MCNB) and in the Institute of Geology and Paleontology of Nanjing (China). A large grouping of a single species of beetles in a piece of amber “could only be explained by mating or pollination reasons”,

reveals Xavier Delclòs, professor at the Department of Earth and Ocean Dynamics and at IRBio, who has studied the pieces deposited in the MCNB. “It is not common to find pieces of amber that have been captured by various organisms. Nor is it easy to discover fossils that describe aspects of the behavior of living beings, and especially those related to pollination, ”explains David Peris, head of the research project on this fossil amber material. Beetles, the first flower pollinators Traditionally, beetles have been considered one of the groups of pollinating insects of the first flowers on Earth. The new study reveals that, in three pieces of amber, the pollen grains found near the beetles correspond to gymnosperm plants (without visible flowers),
