Paleoproteomics characterization of fossil arthropod parasitiformes amber inclusions

In this study, we developed and applied a paleoproteomics approach to study inclusions of fossil arthropod parasitiformes in two Burmese amber (Cretaceous, ca. 124 - 99 mya) pieces. The results supported the identification of Cornupalpatum sp. and the first report of fossil Holothyrida, Neothyridae at both morphological and molecular levels. Identified proteins were analyzed to evaluate evolutionary trees with possible functional implications in biomedicine. Actin proteins were identified in both amber inclusions and may belong to Neothyridae and Cornupalpatum sp., respectively.
