Sulcichnus sigillum ichnosp. nov.
Fig. 4A–C View Fig .
Etymology: After the Latin word sigillum , mark, brand, referring to the branding iron morphology of the groove.
Type material: Holotype, MMPE /Ic003.001.001 (Parque Antena, Estepona) ( Fig. 4C View Fig ) . Paratypes, MMPE /Ic003.002.001 (Arroyo Vaquero, Estepona) ( Fig. 4A View Fig ) , MMPE/Ic003.003.001( Fig. 4B View Fig ).
Type locality: Parque Antena , Estepona Basin, E Andalusia, Spain .
Type horizon: Upper Zanclean (Pliocene) coarse−grained sand levels within conglomerates, Estepona Basin, Málaga ( SE Spain) ( Aguirre et al. 2005) .
Material.—Number of specimens: 1 from Arroyo Vaquero, Estepona; 1 from Padrón, Estepona; 1 from Parque Antena, Estepona; 8 from Velerín, Estepona ( Table 2).
Diagnosis.—Shallow groove parallel to the columella and bending 90 ° close to the calyx, to form a deeper, ring−shaped groove.
Description.—Shallow grooves (1 mm maximum in depth) that run more or less in parallel to the axis of the columella from close to the base of the corallite. They turn a sharp 90 ° to the left when reaching a point a few millimetres from the edge of the calyx, where they deepen (to some 2 mm) and run almost the whole of the perimeter of the corallite, thus taking on the appearance of a branding iron.
Remarks.—This trace has only been identified in the turbinate coral morphologies ( Caryophyllia and Trochocyathus ) ( Table 3). Some Recent specimens seen in the literature also follow this pattern.
Stratigraphic and geographic range.—Zanclean (Early Pliocene) to Recent; worldwide.
