Cells, Collagen Fibrils and Vessels in Dinosaur Bone

  title={Cells, Collagen Fibrils and Vessels in Dinosaur Bone},
  author={Roman Pawlicki and Andrzej Korbel and Henryk Kubiak},
COLLAGEN has been found in mummified human remains several thousand years old, and in mastodon bones preserved under permafrost conditions. It has been stated that bone fragments after glacier preservation had all the appearances of a fresh bone1. Studies on Pleistocene bones have demonstrated that it is also possible to observe collagen and other organic materials in a fossil bone2,3. Electron micrographs of fossil bones of a deer-like animal from the Miocene (25 million years old) revealed…

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 documented to have been

Soft tissue and cellular preservation in vertebrate skeletal elements from the Cretaceous to the present

The results suggest that present models of fossilization processes may be incomplete and that soft tissue elements may be more commonly preserved, even in older specimens, than previously thought.

Preservation of Triceratops horridus Tissue Cells from the Hell Creek Formation, MT

VPSEM and cell isolation results from the Triceratops horn are described, which show remarkable preservation of individual bone osteocytes encapsulated within the stretchy sheets of fibrillar horn bone was observed, as were osteocytes positioned upon sheets of F2 bone adhering to permineralized vessels within the decalcified horn bone.

The mineralized osteocyte: a living fossil.

The significance of the findings demonstrates that a single cell may itself mineralize in vivo via an unknown set of biochemical events, and this unique fossil cell provides a preservation locus within human and mammalian bone, which might be fruitfully targeted in future biomolecular studies.

Fine structure of bone in dinosaurs, birds and mammals

Evidence is presented that canaliculi—the submicrometre-sized channels that interconnect bone cells and vascular canals—and the collagen fibre bundles in bone are differently organized among certain dinosaur lineages, and ornithomimid dinosaurs are more like birds than mammals in these features.

Preservation of biomolecules in cancellous bone of Tyrannosaurus rex

ABSTRACT An exceptionally well preserved specimen of the tyrannosaurid dinosaur Tyrannosaurus rex Osborn shows little evidence of permineralization or other diagenetic effects. It appears that the

Blood vessels and red blood cells preserved in dinosaur bones.

Iron-mediated deep-time preservation of osteocytes in a Middle Triassic reptile bone

Brownish to rust-coloured microbodies, extracted from a Middle Triassic bone of the reptile Nothosaurus, are morphologically consistent with bone cells of present-day vertebrates and the absence of a distinct signal indicating organic molecules suggests that the original bone cells underwent autolysis or other degradative processes before or during mineralization.

Collagen and a Cellulose-like Substance in Fossil Dentine and Bone

THE first direct evidence that certain organic components are retained in the fossil remains of vertebrates comes from the analysis by paper chromatography of specimens of Dinichthys of Middle


The present paper is a preliminary account of the nature of carbonaceous residues from Early Pleistocene bones collected from the Mendivil Ranch locality (Benson fauna) in Southern Arizona.

This demonstration is important as the basis for an investigation of the fine structure of older fossils by progressively decalcifying ultrathin sections to reveal their organic components.


Evidence has been produced to suggest that the immediate cause of many forms of osteoporosis is some local factor affecting the osteocytes, rather than a general chemical effect.

Histology of Mammoth Bone

Compact bone from a frozen Alaskan mammoth was examined histologically and chemically to determine whether there had been any detectable alterations since the death of the animal. Histological
