Conulariid

Conulariid

 

an extinct invertebrate, most often assigned to Coelenterata. The conulariids inhabited the seas from the early Cambrian to the early Triassic. They had a pyramid- or cigarshaped skeleton with a thin wall that was possibly elastic in life. The top part was divided by cross ridges into chambers. Fourfold symmetry is usually characteristic of the skeletal elements. The majority of conulariids led a natatorial mode of existence.

The shale also contains bryozoans, orthoconic cephalopods, rare crinoids and conulariids.
Mergl (2002) proposed that the generally poorly fossiliferous shales with phyllocarids (Caryocaris), graptolites, conulariids, nautiloids and trilobites should be classified as the Rafanoglossa Community within his Paterula Community Group.
Well-diversified trilobites, brachiopods, gastropods, echinoderms, phyllocarids, ostracods, bivalves, agnostids, hyoliths, cephalopods and conulariids, associated with graptolites and ichnofossils, have been studied for more than 150 years (see Barrande 1872; Havlicek & Vanek 1966, 1990; Mikulas 1991; Mergl 2002; Chlupac 2003; Kraft & Kraft 2003; Budil et al.
