The Jehol Biota, an Early Cretaceous terrestrial Lagerstätte: new discoveries and implications

ABSTRACT
Thestudy of the Early Cretaceous terrestrial Jehol Biota, which provides a rare window for reconstruction of
a Lower Cretaceous terrestrial ecosystem, is reviewed with a focus on some of the latest progress. A newly
proposed definition of the biota based on paleoecology and taphonomy is accepted. Although the Jehol
fossils are mainly preserved in two types of sedimentary rocks, there are various types of preservation with a
complex mechanism that remains to be understood. New discoveries of significant taxa from the Jehol
Biota, with an updated introduction of its diversity, confirm that the Jehol Biota represents one of the most
diversified biotas of the Mesozoic. The evolutionary significance of major biological groups (e.g. dinosaurs,
birds, mammals, pterosaurs, insects, and plants) is discussed mainly in the light of recent discoveries, and
some of the most remarkable aspects of the biota are highlighted. The global and local geological,
paleogeographic, and paleoenvironmental background of the Jehol Biota have contributed to the unique
composition, evolution, and preservation of the biota, demonstrating widespread faunal exchanges between
Asia and other continents caused by the presence of the Eurasia–North American continental mass and its
link to South America, and confirming northeastern China as the origin and diversification center for a
variety of Cretaceous biological groups. Although some progress has been made on the reconstruction of
the paleotemperature at the time of the Jehol Biota, much more work is needed to confirm a possible link
between the remarkable diversity of the biota and the cold intervals during the Early Cretaceous. Finally,
future directions for the study of the Jehol Biota are proposed that highlight the great potential of more
comprehensive and multidisciplinary studies to further our understanding of the biological and geological
implications of the Jehol Lagerstätte.
