Aims & Scope✦ Inferred from recent articles

Paleontological Research publishes studies on fossil organisms, including invertebrates like ammonoids, corals, and ostracods, as well as vertebrates such as toothed whales and mammals. The journal also features research on fossil insects, plants, and crinoids. Many articles focus on describing new fossil species and their taxonomic classification, often using detailed morphological analysis and comparative studies with extant relatives. The research frequently involves biostratigraphy, paleoenvironmental reconstructions, and evolutionary insights derived from fossil assemblages.
