03CCF03DFFBA1E4BF9936B6FFE40347A.taxon	description	Glomerula serpentina (GOLDFUSS, 1831). – Jäger: p. 130, pl. 1, fig. 1. M a t e r i a l: One specimen attached to an oyster. 15 tube fragments. D e s c r i p t i o n: Tube circular. Surface smooth. The tube is coiled to form a ball or knots. Lumen circular, a trilobite lumen was not observed in these specimens. Tube diameter ranges from 1.6 to 2.6 mm, in most specimens the diameter is 2 mm. D i s c u s s i o n: Glomerula serpentina belongs among the typical species of nearshore facies of the BCB. Glomerula serpentina (GOLDFUSS) was considered to belong to G. gordialis SCHLOTHEIM by some authors (for example, Regenhardt 1961, Jäger 1983, Ziegler, 1984) Later Jäger (2005) restricted Glomerula gordialis SCHLOTHEIM to Jurassic material and determined Cretaceous specimens as a separate species, G. serpentina. A similar species, Glomerula lombricus (DEFRANCE), is distinguished by its small tube diameter which is normally less than circa 1 mm. The systematic position of the genus Glomerula is very problematic. The genus Glomerula has survived from the Hettangian to the Recent, and it is most common and geographically widespread from the Upper Toarcian until the Eocene. Jäger (personal communication) predicts that the genus Glomerula existed as a large number of species, but that it is nearly impossible to separate them because the construction of the tube is so simple and the morphologic variation between specimens even in one sample is extremely wide. Jäger (1983, 1993, 2005 and personal communication) mentioned that the genus Glomerula did not possess a trilobate lumen even in the Jurassic. From the uppermost Valanginian onwards, trilobate lumina are present, but they are still rare in most samples from the Lower Cretaceous and even in some samples from the Upper Cretaceous. The ability of the animal to produce a tube which in some sections has a trilobate lumen seems to be true phylogenetic progress. Jäger (2005 and personal communication) gave different names to species from the Jurrassic and those from the Cretaceous to Eocene. Trilobate lumina may be present in Glomerula plexus (SOWERBY), in Glomerula serpentina (GOLDFUSS), and in Glomerula lombricus (DEFRANCE), but trilobate lumina are more frequent in G. serpentina than in G. lombricus. Glomerula plexus (SOWERBY) is gregarious, consisting of smooth uniform tubes, each measuring 1 - 2 mm in diameter, many of these together forming large irregular masses of a bulbous or elongated shape, reaching dimensions of up to 5 cm in the BCB and even larger in some localities, predominantly in the Santonian and Campanian of northern Germany, England, and southern Sweden. Apart from these typical large clusters consisting of dozens or even hundreds of tubes, in many localities it is possible to find two, three or four tubes fixed upon each other. Formally, these small clusters should be named „ plexus “, but in reality they probably represent only dense populations of the „ normal “ serpentina and lombricus (Jäger, personal communication).	en	Kočí, Tomáš (2012): Sabellidae And Serpulidae (Polychaeta, Canalipalpata) From The Locality Kaňk - Na Vrších In Kutná Hora (Upper Cenomanian - Lower Turonian, Bohemian Cretaceous Basin - The Czech Republic).

03CCF03DFFB81E4AFAC3680DFBE330F1.taxon	description	1984 Eoplacostegus zbyslavus n. sp. – Ziegler: p. 236, pl. 6, figs 1 - 2. M a t e r i a l: One well preserved specimen. Two fragments of the erect free tube portion. D e s c r i p t i o n: The free subtriangular tube portion is steeply erect and is twisted around its longitudinal axis. The tube diameter is 1.6 mm in the anterior tube portion and 1.5 and 1.9 mm in the middle part. Lumen circular. The posterior tube portion is coiled to form a planispiral 3.9 mm in diameter. The surface bears fine transversal furrows and three distinct longitudinal lines situated between three rounded longitudinal edges which give the tube a rounded triangular cross-section. D i s c u s s i o n: Placostegus zbyslavus (ZIEGLER) belongs among the smaller species of the genus Placostegus. The specimens described by Ziegler (1984) do not bear transversal furrows in the posterior fixed tube portion. Placostegus dentatus (REGENHARDT) has a triangular cross-section, but lacks transversal ornamentation. Placostegus velimensis (JÄGER AND KOČÍ, 2007) is larger and has a rounded rectangular cross-section.	en	Kočí, Tomáš (2012): Sabellidae And Serpulidae (Polychaeta, Canalipalpata) From The Locality Kaňk - Na Vrších In Kutná Hora (Upper Cenomanian - Lower Turonian, Bohemian Cretaceous Basin - The Czech Republic).

Ditrupa tricostata (GOLDFUSS), 1841. – Ziegler: pp. 14 - 18, figs 2 - 3. 1984 Ditrupa subtorquata (MÜNSTER), 1831. – Ziegler: pp. 238 - 239, Ditrupa tricostata (GOLDFUSS), 1841. – Ziegler: p. 239, pl. 6, figs 8 - 9. Pyrgopolon (Septenaria) cf. tricostata (GOLDFUSS). – Kočí: pp. 124 - 125, figs 5 - 6. M a t e r i a l: One complete specimen, 30 specimens of the free anterior tube portion, 4 incomplete specimens of the free anterior tube portion and attached posterior tube portion, 26 tube fragments. D e s c r i p t i o n: Posterior tube portion is attached to the substrate; the cross-section of this part is triangular, and there is one median keel. Anterior tube portion freely erect with five rounded keels respectively, four lobes and a very fine distinct median keel. Diameter of the anterior tube portion 2.6 mm. Lumen circular, 2.4 mm in diameter. A groove is present on the underside between the lower lateral lobes. D i s c u s s i o n: These specimens are very similar to Ditrupa (Pentaditrupa) iubata REGENHARDT, 1961 from the Turonian of Troo, Loire-et-Cher, France, which has four rounded keels (lobes) and a very distinct dorsal keel. The cross-section is pentangular and there is no transversal ornamentation. The holotype differs from the specimens from Kaňk due to its larger median keel, and from Regenhardt´s description it is clear that the anterior tube portion was still attached to the substrate. In contrast the specimens from Kaňk have anterior tube portions which are free and erect above the substrate. Moreover, the specimens from Kaňk do not belong to the typical tricostata species from the Cenomanian of Essen in Germany. According to their morphological features they belong to the subgenus Pyrgopolon (Septenaria), see (Jäger, 1983, 2005; Jäger and Breton, 2002). In the BCB, Pyrgopolon (Septenaria) cf. tricostata was found in nearshore localities, e. g. Velim, Nová Ves, Kamajka, and Chrtníky. The specimen from Nová Ves near Kolín which Ziegler (1984) described as Ditrupa iubata (REGENHARDT) (NM- O 5391) is not serpulid. The specimen which according to its registration number NM-O 5363 should be, is not the original specimen figured by Ziegler (1984) on his pl. 6, fig. 7 as Ditrupa subtorquata from Nová Ves. In addition, the original specimens NM-O 5394 and NM-O 5395 determined by Ziegler as Ditrupa tricostata from Velim, all are very similar to the specimens from Kaňk and represent the same species, which is, however, neither subtorquata nor tricostata. Ziegler (1967, 1984) described specimens from the BCB as belonging to the genus Ditrupa, but this is a misinterpretation, because in contrast to Ditrupa, the posterior tube portion is attached to the substrate, whereas the shape is similar to the genus Pyrgopolon and especially the subgenus Septenaria. The species Ditrupa subtorquata and Ditrupa schlotheimi clearly belong to the genus Ditrupa.	en	Kočí, Tomáš (2012): Sabellidae And Serpulidae (Polychaeta, Canalipalpata) From The Locality Kaňk - Na Vrších In Kutná Hora (Upper Cenomanian - Lower Turonian, Bohemian Cretaceous Basin - The Czech Republic).

03CCF03DFFBF1E4DFAD36C61FD253A7A.taxon	description	2010 Pyrgopolon ziegleri sp. n. – Kočí: p. 125, figs 7 - 8. M a t e r i a l: One complete specimen. Two fragments of tube. D e s c r i p t i o n: Fixed tube portion large, smooth, triangular in cross-section, bears a distinct median keel. There is no transversal ornamentation. Tube width at the anterior end of the base 13.2 mm, corresponding tube height 12.6 mm. Towards the posterior, the tube is considerably narrower, and the height is only 6.7 mm. Lumen circular, 3.96 mm in diameter. The lumen is situated in an excentric position, near to the keel. Immediately below the aperture, there is a smaller tall but narrow chamber measuring circa 2 mm, and between that chamber and the tube’s base there is a fine groove. Free tube portion is unknown. D i s c u s s i o n: This species includes the largest specimens with triangular cross-section in the BCB and is characterized by its shape and size. Pyrgopolon (Septenaria) ares (ZIEGLER) differs by the position of its lumen and by its narrower longitudinal keel. Pyrgopolon sp. A 1, Pyrgopolon sp. A 2 and Pyrgopolon sp. B from the nearshore locality Velim (see Kočí, 2007 a) differ also in the position of the lumen, and partly by their tube morphology. Pyrgopolon (Septenaria) marechali (JÄGER et BRÉTON) from the Lower Cenomanian of Normandy, France, is even larg- er, and its tube is much more rounded. Pyrgopolon (Septenaria) polyforata (JÄGER) differs by its specific ornamentation. Pyrgopolon (Septenaria) macropus (SOWERBY) has a pentagonal to heptagonal cross-section and a more prominent keel (Jäger, 2005, pl. 9, fig. 5 a). The tube of Pyrgopolon (Septenaria) macropus is attached to the substrate by its posterior tube portion and its anterior tube portion is erect above the substrate. The same is seen in Pyrgopolon (Septenaria) erecta (GOLDFUSS), which is distinguished by its larger tube diameter which may reach 14 mm. The subgenus Pyrgopolon (Septenaria) is most common in transgression facies (Jäger, personal communication).	en	Kočí, Tomáš (2012): Sabellidae And Serpulidae (Polychaeta, Canalipalpata) From The Locality Kaňk - Na Vrších In Kutná Hora (Upper Cenomanian - Lower Turonian, Bohemian Cretaceous Basin - The Czech Republic).
