Characterization on organic matrix proteins enclosed in high Mg-calcite crystals of the coralline sponge Spirastrella (Acanthochaetetes) wellsi
Bergbauer, Matthias; Lange, Robert; Reitner, Joachim(Globale und regionale Steuerungsfaktoren biogener Sedimentation, 1996)
Protein components found in freeze-dried specimens of the coralline sponge Spirastrella (Acanthochaetetes) wellsi were separated and characterized . Proteins extracted from skeleton crystals (matrix proteins) contained ... -
Chitinobelus acifer Fischer 1981, ein Belemnoteuthide (Coleoidea) mit Epirostrum
The "unusual belemnite" Chitinobelus acifer FISCHER with an "almost purely organic, pinlike epirostrum" and a "calcitic primary rostrum" (FISCHER 1981: 142) is attributed to the order Belemnoteuthida STOLLEY 1919. ... -
Coleoids from the Lower Devonian Black Slate ("Hunsrück-Schiefer") of the Hunsrück (West Germany)
Bandel, Klaus; Reitner, Joachim; Stürmer, Wilhelm (Neues Jahrbuch für Geologie und Paläontologie. Abhandlungen, 1983)
Three new genera of endocochleate cephalopods from the Lower Devonian cast new light on the evolution of modern and fos sil coleoids. Protoaulacoceras n. g. represents the r03trum-bearing line of aulacocerid-belemnitid ... -
Coralline demosponges ; a geobiological portrait
Reitner, Joachim; Wörheide, Gert
; Lange, Robert; Schumann-Kindel, Gabriela (Bulletin / The Tohoku University Museum, 2001)
The polyphyletic coralline demosponges possess a calcareous basal skeleton of 4 major morphotypes. Each has its own phylogenetic history, with different mechanisms of formation. One extant taxon of each skeletal type has ... -
Die "Weichteilbelemniten" des Posidonienschiefers (Untertoarcium) von Holzmaden (Baden-Württemberg) sind Fälschungen
The "soft-part-belemnites" In the Holzmaden Posidonia Shales are forged. · Soft-parts of Phragmoteuthis conocauda (QUENSTEDT) have been compounded with belemnite rostra of Passaloteuthis paxillosa (SCHLOTHEIM). The ...
