Collagens are the most abundant protein in the animal kingdom. Collagens form the structural framework of connective tissues such as bones, tendons and skin and play important biomechanical role in supporting tissue functions. The preservation of collagen in deep time is a topic of intense debate. Here we provide indisputable evidence of the presence of collagen in Early Eocene fish vertebrae using online pyrolysis-comprehensive two dimensional gas chromatography-time-of-flight mass spectrometry and immunofluorescence studies. The presence...
