Aims & Scope✦ Inferred from recent articles

Lethaia publishes research on paleontology, focusing on the study of fossil organisms and their ancient environments. Recent articles investigate the palaeobiogeographical distribution and evolution of various fossil groups, including acritarchs, trilobites, and graptolites, across different geological periods like the Ordovician and Devonian. The journal also features studies on taphonomy, the processes of fossilization and preservation, with examples from diverse locations and time periods, including exceptional preservation of soft-bodied organisms and the formation of fossil deposits in caves and marine settings. Additionally, Lethaia includes research on palaeoecological reconstructions, the evolution of marine communities, and the development of quantitative stratigraphical methods for correlation and dating of rock sequences.
