Description

Thyrsoporella Gümbel, 1871 Trinocladus Raineri, 1922

Fig. 5a

Remarks: The available tangential section does not allow the recognition of the lateral morphology and number of orders. We can just mention similarities to sections of Trinocladus perplexus Elliott (Elliott, 1955; Deloffre and Fourcade, 1994) and Thyrsoporella longa Radoičić, both described from Paleocene strata of Iraq. Granier and Braik (2002) already put up for discussion the possibility that some of the forms described as Trinocladus perplexus are identical to the thyrsoporellids reported by Radoičić (1990). If verified, it would then result in the new combination Thyrsoporella perplexa (Elliott) due to priority reason. On the other side, the existence of three orders of laterals (> Trinocladus) has been demonstrated by Deloffre and Fourcade (1994, transverse section in pl. 1, fig. 16) in material from Mexico excluding the belonging to Thyrsoporella (> 3 orders).
