2018 journal article

Preservation potential of keratin in deep time

PLOS ONE, 13(11), e0206569.

By: M. Schweitzer n , W. Zheng n, A. Moyer*, P. Sjövall * & J. Lindgren *

Ed(s): Y. Mishra

MeSH headings : Animals; Antibodies; Feathers / chemistry; Feathers / immunology; Feathers / ultrastructure; Fossils / ultrastructure; Hot Springs; Hot Temperature; Keratins / chemistry; Keratins / immunology; Tetrahydroisoquinolines; Time Factors
TL;DR: The data support the hypothesis that keratin, particularly the β-keratin that comprises feathers, has potential to preserve in fossil remains and stress the importance of employing realistic conditions such as sediment burial when designing experiments intended as proxies for taphonomic processes occurring in the fossil record.

Molecular evidence of keratin and melanosomes in feathers of the Early Cretaceous bird Eoconfuciusornis

PROCEEDINGS OF THE NATIONAL ACADEMY OF SCIENCES OF THE UNITED STATES OF AMERICA, 113(49), E7900–E7907.

By: Y. Pan *, W. Zheng n, A. Moyer n, . Jingmai K. O'Connor *, M. Wang *, X. Zheng *, X. Wang *, E. Schroeter n, Z. Zhou*, M. Schweitzer n 

author keywords: keratinous protein; immunogold; ChemiSTEM; melanosome; Early Cretaceous
MeSH headings : Animals; Biological Evolution; Birds / anatomy & histology; Feathers / ultrastructure; Fossils / ultrastructure; Keratins; Melanosomes
TL;DR: This work represents the oldest ultrastructural and immunological recognition of avian beta-keratin from an Early Cretaceous (∼130-Ma) bird and sheds new light on molecular preservation within normally labile tissues preserved in fossils. (via Semantic Scholar)

2015 review

Interpreting melanin-based coloration through deep time: A critical review

[Review of ]. Proceedings of the Royal Society of London. Series B, 282(1813), 20150614.

By: J. Lindgren *, A. Moyer n, M. Schweitzer n , P. Sjovall *, P. Uvdal *, D. Nilsson *, J. Heimdal*, A. Engdahl * ...

author keywords: bacteria; eumelanin; melanosome; pheomelanin; pyomelanin; vertebrate
MeSH headings : Animals; Biological Evolution; Fossils; Melanins / chemistry; Melanosomes / physiology; Microbodies / chemistry; Pigmentation; Vertebrates / physiology
TL;DR: Both vertebrate and microbial melanization are surveyed, and the conflicts influencing assessment of microbodies preserved in association with ancient animal soft tissues are explored, and an integrated morphological and geochemical approach for detecting endogenous pigment remains and associated microstructures in multimillion-year-old fossils is outlined.

Melanosomes and ancient coloration re-examined: A response to Vinther 2015

BioEssays, 37(11), 1174–1183.

By: M. Schweitzer n , J. Lindgren * & A. Moyer n

author keywords: ancient color; fossil feather; melanin; melanosome; microbe; molecular paleontology; parsimony
MeSH headings : Animals; Humans; Melanins / analysis; Pigmentation
TL;DR: Evidence for ancient melanosomes is re‐examine in light of information reviewed in Vinther (2015), and literature regarding the preservation potential of microorganisms and their exopolymeric secretions. (via Semantic Scholar)
