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...

Data from: An enigmatic new ungulate-like mammal from the early Eocene of India

Shawn Zack, Kenneth Rose, Luke Holbrook, Kishor Kumar, Rajendra Rana & Thierry Smith
We report on a new genus and species of herbivorous mammal, Pahelia mysteriosa, from the early Eocene Cambay Shale Formation, Tadkeshwar Lignite Mine, Gujarat, India. The new taxon, approximately the size of a small phenacodontid (e.g., Ectocion parvus), is represented by three mandibular fragments, the most complete of which documents nearly the entire symphysis and mandibular body plus P3-M3. Pahelia has incipiently selenolophodont molars with strong exodaenodonty, absent paraconids, weak but distinct entolophids, and prominent...
