Recurrent constructional pattern of the crustacean burrow Sinusichnus sinuosus from the Paleogene and Neogene of Spain

Abstract

New occurrences of Sinusichnus sinuosus described in the Cenozoic

Rosarichnoides sudeticus igen. et isp. nov. and associated fossils from the Coniacian of the North Sudetic Synclinorium (SW Poland)

“…Fürsich (1973) and Schlirf (2000) pro posed synonymizing these ichnogenera, but this was not ac cepted (see Bromley and Frey, 1974;Bromley, 1996;Schlirf, 2005). Ac cord ing to Gibert (1996), Sinusichnus should also be in cluded to this group (see Belaústegui et al, 2014). Gyrolithes Saporta, 1884, Ardelia (Cham ber lain andBaer, 1973) and Parmaichnus Pervesler and Uchman, 2009 are also pro posed to rep re sent ophiomorphids (Bromley and Frey, 1974;Netto et al, 2007;Seilacher, 2007;Pervesler and Uchman, 2009).…”

The trace fossilSinusichnusfrom the Upper Ordovician of Anticosti Island, eastern Canada

“…Sinusichnus sinuosus (Upper Cretaceous to Neogene) and S. priesti (Upper Cretaceous) are interpreted as the product of burrowing decapod crustaceans (Gibert 1996;Kappel 2003;Buatois et al 2009;Belaústegui et al 2014), while S. seilacheri (Middle Triassic) is interpreted to represent behavioural convergence produced by isopod crustaceans (Knaust et al 2016). The Upper Ordovician material is strikingly similar to its Triassic counterpart and therefore is attributed to the same ichnospecies.…”

“…Sinusichnus is a comparatively young ichnotaxon, with its type ichnospecies S. sinuosus originally and mainly described from France and Spain (Gibert 1996;Gibert et al 1999;Knaust et al 2014;Belaústegui et al 2014Belaústegui et al , 2015. Subsequently, Sinusichnus was also recognized in Germany (Kappel 2003 seilacheri is the first evidence of Sinusichnus from North America.…”
