Discovery of 505-million-year old chitin in the basal demosponge Vauxia gracilenta - Supplementary information
Hermann Ehrlich,J. Keith Rigby,Joseph P. Botting,Mikhail V. Tsurkan,Carsten Werner,Petra Schwille,Zdeněk Petrášek,Andrzej Pisera,Paul Simon,V N Sivkov,Denis V. Vyalikh,Serguei L. Molodtsov,Denis V. Kurek,Martin Kammer,S. Hunoldt,René Born,Dawid Stawski,A. Steinhof,Vasilii V. Bazhenov,Thorsten Geisler +19 more
TL;DR: The discovery of 505–million-year-old chitin is presented, found in exceptionally well preserved Vauxia gracilenta sponges from the Middle Cambrian Burgess Shale, indicating that, given the right fossilization conditions, chit in is stable for much longer than previously suspected.
Journal ArticleDOI
Chitin-based scaffolds are an integral part of the skeleton of the marine demosponge Ianthella basta
Eike Brunner,Hermann Ehrlich,Peter J. Schupp,René Hedrich,S. Hunoldt,Martin Kammer,Susanne Machill,Silvia Paasch,Vasilii V. Bazhenov,Denis V. Kurek,T. Arnold,S. Brockmann,Michael Ruhnow,René Born +13 more
TL;DR: It is shown that a filigree chitin-based scaffold is an integral component of the I. basta skeleton and can be isolated from the sponge skeletons using an isolation and purification technique based on treatment with alkaline solutions.
Journal ArticleDOI
Three-dimensional chitin-based scaffolds from Verongida sponges (Demospongiae: Porifera). Part I. Isolation and identification of chitin.

Molodtsov,Heike Meissner,Gert Richter,Eric Steck,Wiltrud Richter,S. Hunoldt,Martin Kammer,Silvia Paasch,V. Krasokhin,Greta R. Patzke,Eike Brunner +28 more
TL;DR: A detailed study of the structural and physico-chemical properties of three-dimensional skeletal scaffolds of the marine sponges Aiolochroia crassa, Aplysina aerophoba, and A. cavernicola shows that these fibrous scaffolds have a multilayered design and are made of chitin.
Journal ArticleDOI

TL;DR: Using slow-alkali etching of biosilica, the organic fraction was revealed to be dominated by a hydroxylated fibrillar collagen that contains an unusual [Gly-3Hyp-4Hyp] motif, which is speculated to be predisposed for silica precipitation, and provides a novel template for biosilicification in nature.
