NOTE: This article is by a controversial researcher. Posting it to the DML is not an endorsement of his ideas expressed outside of scientific literature. This paper does not express the researcher's personal interpretations of fossil dates. Microscopy Today is a semi-technical trade magazine and not a peer-reviewed purely technical journal,Âso this article would have less formal status but still may be of interest. Claims of preserved internal soft tissue and organic residues or other nonmineralized structures in dinosaur bone fossils have been made by a number of paleontologists and other researchers.

First Report of Peripheral Nerves in Bone from Triceratops horridus Occipital Condyle.
Microscopy Today 29(2): 20-25

https://www.cambridge.org/core/journals/microscopy-today/article/first-report-of-peripheral-nerves-in-bone-from-triceratops-horridus-occipital-condyle/AE0FA022206E67ED3B53A24A9071967D



Peripheral nerves in vertebrate systems have been studied for centuries. Nerve anatomy, including the connective tissues that cushion nerves, are well described in the literature. The outer connective tissues, known as the epineurium and perineurium, include a double layer of collagen fibers that form a double helical wrapping that is visible with polarized light microscopy and by other contrast methods. This wrapping is a diagnostic characteristic of nerve tissues. Decades of research into dinosaur bones have produced interesting endocasts of probable brain morphology, but no soft and flexible nerve tissues have been reported from dinosaur remains. In this study we provide evidence of nerve fragments, characterized by a double helical wrapping of collagen fibers, from a Triceratops condyle collected at the Hell Creek Formation, MT. Based on comparison with nerves from an avian model we conclude that these are fragments of nerves that once resided in vivo in Triceratops.
