Fossil proteins are valuable tools in evolutionary biology. Recent technological advances
and better integration of experimental methods have confirmed the feasibility of …

Fossils were thought to lack original organic molecules, but chemical analyses show that
some can survive. Dinosaur bone has been proposed to preserve collagen, osteocytes, and …

Many fossil insects show monochromatic colour patterns that may provide valuable insights
into ancient insect behaviour and ecology. Whether these patterns reflect original …

In the most recent three decades, there has been an outpouring of research on the
preservation of cells and soft tissues within fossil bones. Cells and soft tissues that are …

Background Birds are key indicator species in extant ecosystems, and thus we would expect
extinct birds to provide insights into the nature of ancient ecosystems. However, many …

Exceptional fossils can preserve diagenetically‐altered biomolecules. Understanding the
pathways that lead to such preservation is vital to utilizing fossil information in evolutionary …

Ancient protein analysis is a rapidly developing field of research. Proteins ranging in age
from the Quaternary to Jurassic are being used to answer questions about phylogeny …

Multiple fossil discoveries and taphonomic experiments have established the durability of
keratin. The utility and specificity of antibodies to identify keratin peptides has also been …

Fossils are a key source of data on the evolution of feather structure and function through
deep time, but their ability to resolve macroevolutionary questions is compromised by an …

We address the identity of putative ovarian follicles in Early Cretaceous bird fossils from the
Jehol Biota (China), whose identification has previously been challenged. For the first time …
