Heteromorphs are ammonoids forming a conch with detached whorls (open coiling) or non‐planispiral coiling. Such aberrant forms appeared convergently four times within this extinct group of cephalopods. Since Wiedmann's seminal paper in this journal, the palaeobiology of heteromorphs has advanced substantially. Combining direct evidence from their fossil record, indirect insights from phylogenetic bracketing, and physical as well as virtual models, we reach an improved understanding of… Expand
The balancing act of Nipponites mirabilis (Nostoceratidae, Ammonoidea): Managing hydrostatics throughout a complex ontogeny
Virtual, 3D models of Nipponites mirabilis were used to compute various hydrostatic properties through 14 ontogenetic stages, suggesting that NIPPonites maintained a delicate hydrostatic balancing act throughout its ontogeny in order to facilitate this mode of life. Expand
The balancing act of Nipponites mirabilis (Nostoceratidae, Ammonoidea): managing hydrostatics during a complex ontogenetic trajectory
Virtual, 3D models of Nipponites mirabilis were used to compute various hydrostatic properties through 14 ontogenetic stages, suggesting that NIPPonites maintained a delicate hydrostatic balancing act throughout its ontogeny in order to facilitate this mode of life. Expand
Fossilized leftover falls as sources of palaeoecological data: a ‘pabulite’ comprising a crustacean, a belemnite and a vertebrate from the Early Jurassic Posidonia Shale
Especially in Lagerstätten with exceptionally preserved fossils, we can sometimes recognize fossilized remains of meals of animals. We suggest the term leftover fall for the event and the termExpand
Vertical escape tactics and movement potential of orthoconic cephalopods
The current experiments suggest that orthocones sacrifice horizontal mobility and maneuverability in exchange for highly streamlined, vertically-stable, upwardly-motile conchs. Expand
Preservation of nautilid soft parts inside and outside the conch interpreted as central nervous system, eyes, and renal concrements from the Lebanese Cenomanian
Nautilid, coleoid and ammonite cephalopods preserving jaws and soft tissue remains are moderately common in the extremely fossiliferous Konservat-Lagerstätte of the Hadjoula, Haqel and Sahel AalmaExpand


Morphological diversity of the jaws of Cretaceous Ammonoidea
Jaws (beaks) and radula are occasionally preserved within the body chambers of ammonoids whose exact taxonomic relationships are known. Based on such in situ material, ammonoid jaws from 26 LateExpand
The black layer in cephalopods from the German Muschelkalk (Triassic)
Thin, dark, probably phosphatic coatings were found on the dorsum in front of and sometimes behind the aperture of 50 specimens of Paraceratites and Ceratites (Ammonoidea) belonging to 14 species andExpand
Key innovations in Mesozoic ammonoids: the multicuspidate radula and the calcified aptychus
A nearly complete radula with seven elements per row preserved inside of an isolated, bivalved, calcitic lower jaw (= aptychus) of the Late Jurassic ammonite Aspidoceras is described from theExpand
Heteromorph Ammonoids of the Triassic : A Review
Tiny heteromorphs that suddenly appeared ai the end of the Norian possessed semievolute, com­ pletely straight or slightly curved, twisted or lurriconic shells, with coarse ornamentation and a simpleExpand
The Jaw Apparatus of the Heteromorphic Ammonite Australiceras whitehouse, 1926 (Mollusca: Cephalopoda) from the Aptian of the Volga Region
This is one of the first finds of paired lower and upper jaws in heteromorphic ammonoids, the paleobiology of which, including locomotion and feeding habits, is poorly understood. Expand
Regurgitalites – a window into the trophic ecology of fossil cephalopods
Fossil oral ejecta that exclusively contain bivalved calcitic lower jaws of ammonites (=aptychi) from Late Jurassic Solnhofen-type deposits of southern Germany are described. Based on the symphysisExpand
Pelagic palaeoecology: the importance of recent constraints on ammonoid palaeobiology and life history
Various lines of evidence suggest that different groups of ammonoids had quite different ecologies, but shell shape alone can only give upper constraints on ammonoid capabilities, a matter that needs to be considered when interpreting their diversity and evolutionary history. Expand
Anatomy and evolution of the first Coleoidea in the Carboniferous
It is suggested that conch internalization happened rather suddenly including early growth stages while the ink sac evolved slightly later, as well as the timing of other important steps in early coleoid evolutionary. Expand
Commensal anomiid bivalves on Late Cretaceous heteromorph ammonites from south‐west Japan
The heteromorph ammonite Pravitoceras sigmoidale from the Upper Cretaceous Seidan Formation in south-west Japan is frequently encrusted by sessile anomiid bivalves, suggesting that the encrustation occurred not on post-mortem floating or sunken carcasses but on live conchs and that these organisms were rapidly buried by turbidity current deposits shortly after death.

Cephalopod origin and evolution: A congruent picture emerging from fossils, development and molecules
A growing body of evidence from the fossil record, embryology and Bayesian molecular divergence estimations provides a comprehensive picture of cephalopods' origins and evolution. Expand
