4], pre-existing fabrics and structures are rotated into the BHSZ, and superposed anti-dockwise-younging crenulations and mesoscopic folds formed within the BHSZ and overprint [D.
Later deformation produced boudins, kink bands, crenulations, fractures, and faults.
71), larger rakers on both epibranchial and ceratobranchial possess a row of small, bluntly pointed crenulations
along their medial surfaces (Fig.
Comparativement aux autres dents de plesiosaures, ces specimens ressemblent beaucoup aux dents d'elasmosaures: leur surface exterieure est lisse et leur surface interieure est crenelee, les crenulations
s'etendant presque jusqu'a la pointe de la dent.
From Latin 'ramus' (branch) and 'ramosus' (full of branches), referring to the shape of marginal crenulations
on dentine tubercles.
The small scale folding of the schistosity plane produced crenulation
cleavage, accompanied by segregation of quartz into horizontal layers.
The ventral edge is broadly excavated, with irregular crenulations
in the posterior half to two-thirds.
truncata, a short, deep concave cup-like mesal ventral groove apically, anterior ventral edge concave, movable finger with large primary tooth, smaller anterior tooth, single intermediate tooth separated from primary tooth, crenulations
on the anterior dorsal edge; obscure to small fondal notch (Fig.
of this fabric are widely developed, but are typically observable only in thin section.
However, details of the tubercles (morphology and number of radial ribs, crenulations
, ramifications, microtubercles and plumose wrinkles) are species-level characters.
indica but differs in having dark brown color, a row of paler area along the marginal crenulations
, tessellated dorsum, and by the absence of tubercles on submedian area of abdominal segments.
Irregularly and smoothly crenulate, 15-16 crenulations
