2019 journal article
Paleoproteomics of Mesozoic Dinosaurs and Other Mesozoic Fossils
PROTEOMICS, 19(16), 1800251.
author keywords: dinosaurs; fossil; mesozoic; protein; soft tissues
MeSH headings : Animals; Biological Evolution; Bone and Bones / anatomy & histology; Bone and Bones / metabolism; Dinosaurs / anatomy & histology; Dinosaurs / classification; Dinosaurs / metabolism; Fossils; Mass Spectrometry / methods; Paleontology / methods; Proteins / analysis; Proteomics / methods
TL;DR:
The power and potential of a molecular approach to Mesozoic fossils is discussed, and some criteria for assessing the presence of endogenous biomolecules in very ancient fossil remains are suggested as a starting framework for such studies.

2015 journal article
Mass Spectrometry and Antibody-Based Characterization of Blood Vessels from Brachylophosaurus canadensis
JOURNAL OF PROTEOME RESEARCH, 14(12), 5252–5262.
author keywords: Brachylophosaurus canadensis; blood vessels; dinosaur; cytoskeleton; actin; tubulin; myosin; tropomyosin; tap honomy; preservation
MeSH headings : Actins / genetics; Actins / isolation & purification; Amino Acid Sequence; Animals; Blood Vessels / anatomy & histology; Blood Vessels / metabolism; Blood Vessels / microbiology; Bone and Bones / blood supply; Chickens; Dinosaurs / anatomy & histology; Dinosaurs / genetics; Dinosaurs / metabolism; Fluorescent Antibody Technique / methods; Fossils / anatomy & histology; Mass Spectrometry; Models, Biological; Molecular Sequence Data; Myosins / genetics; Myosins / isolation & purification; Phylogeny; Proteomics / methods; Sequence Alignment; Species Specificity; Struthioniformes; Tropomyosin / genetics; Tropomyosin / isolation & purification; Tubulin / genetics; Tubulin / isolation & purification
TL;DR:
Test the hypothesis that dinosaur cortical bone fragments recovered after demineralization are endogenous and thus retain proteins in common with extant archosaur blood vessels that can be detected with high-resolution mass spectrometry and confirmed by immunofluorescence and two lines of evidence support this hypothesis.

Molecular analyses of dinosaur osteocytes support the presence of endogenous molecules
BONE, 52(1), 414–423.
author keywords: Osteocytes; Fossil; Dinosaur; T. rex; Ancient proteins; Ancient DNA
MeSH headings : Animals; Dinosaurs; Mass Spectrometry; Osteocytes / chemistry
TL;DR:
These data are the first to support preservation of multiple proteins and to present multiple lines of evidence for material consistent with DNA in dinosaurs, supporting the hypothesis that these structures were part of the once living animals.

2011 journal article
Histological, chemical, and morphological reexamination of the "heart" of a small Late Cretaceous Thescelosaurus
NATURWISSENSCHAFTEN, 98(3), 203–211.
author keywords: Ornithischia; Computed tomography; X-ray diffraction; X-ray photoelectron spectroscopy
MeSH headings : Animals; Dinosaurs / anatomy & histology; Fossils; Heart / anatomy & histology; Heart / diagnostic imaging; Microscopy, Electron, Scanning; Myocardium / chemistry; Myocardium / ultrastructure; Photoelectron Spectroscopy; Tomography, X-Ray Computed; X-Ray Diffraction
TL;DR:
The hypothesis that this Thescelosaurus has a preserved heart was controversial, and therefore, the hypothesis was reexamined using higher-resolution computed tomography, paleohistological examination,X-ray diffraction analysis, X-ray photoelectron spectroscopy, and scanning electron microscopy for detailed morphological and chemical examination beyond what was provided in the original work.
