and four left in open nomenclature. Among the six positively identified acritarch species, three have both dubious chronostratigraphic significance and non-distinct morphology (e.g.,
Veryhachium triangulatum, Veryhachium minutum, and Leiosphaeridia ketchenata), and the other three (Diexallophasis denticulata[=Evittia remota], Multiplicisphaeridium raspa, andTylotopalla caelamenicutis) cross the Ordovician–Silurian boundary in the Bohemian sections, and are also known to occur commonly in Silurian strata in other localities.

和四个左在打开的命名法。除积极查明疑源类的六种，三有可疑年代地层学意义和非独特形态 (e.g.,
Veryhachium triangulatum，Veryhachium minutum 和 Leiosphaeridia ketchenata) 和其他三个 (Diexallophasis 荬 [= Evittia 延胡索]，Multiplicisphaeridium raspaandTylotopalla caelamenicutis) 在波希米亚的部分中，Ordovician–Silurian 过境，也众所周知，通常发生在其他地区志留纪地层中。

四留在开放式命名法。在六个疑源类物种肯定地识别，3兼得可疑年代地层意义和非明显的形态（例如，
Veryhachium triangulatum，Veryhachium minutum，并Leiosphaeridia ketchenata），和其他三个（Diexallophasis北球[= Evittia remota]，Multiplicisphaeridium raspa，andTylotopalla caelamenicutis）交叉波西米亚部分奥陶-志留系界线，并且也被称为通常发生在志留纪地层中的其他地方。

在开放的命名四左。六确认疑源类物种中，三有两个可疑的年代地层意义和非独特的形态（例如，
veryhachium triangulatum，veryhachium蕨，和ketchenata Leiosphaeridia），和三（diexallophasis齿[ = evittia remota ]，multiplicisphaeridium raspa，andtylotopalla caelamenicutis）在波希米亚剖面奥陶系–志留系界线，也被称为在其他地区志留系地层常发生。
