Discovery of proteinaceous moieties in Late Cretaceous dinosaur eggshell Open
The documentation of proteinaceous soft tissues in fossils from deep time remains controversial. Often this has been attributed to the laboratory or other modes of modern contamination. Here we provide incontrovertible evidence for the pre…

Chemical evidence for the preservation of collagen in Eocene turtle shell using Py-GCxGC-TOFMS Open
<p>Studies on organic preservation in fossil tissues have been a contentious topic, as fossils have been thought to preserve little, if any, organic content after diagenesis. Several studies have previously reported the presence of c…

Evolution of plant terpenoids on a ‘biotic ferry’ Open
<p>Palaeogegraphic model suggests that the Indian plate was separated from Gondwana during Late Jurassic and started moving towards the northern hemisphere during the Early Cretaceous and remained as an island continent during the en…
