Katian in units P/7 and P/13. Only few coral colonies were observed from the Silurian part of the sequence
(P/16). REED (1912) described Streptelasma sp. aff. S. corniculum, Streptelasma sp. or Zaphrentis sp.,
Streptelasma? sp., Heliolites depauperata, Heliolites? sp., Lyopora? sp., Propora himalaica, Calapoecia? sp.,
Protaraea kanaurensis, Favosites spitiensis, Halysites catenularia var. kanaurensis, Halysites wallichi, Halysites sp.
and listed the species of Plasmoporella from the Takche Member. Among them, the species, except for
Streptelasma? sp., Heliolites depauperata, Lyopora? sp. and Plasmoporella sp., were ones that REED (1912)
described from HAYDEN’S Horizon 6 as the Silurian species. According to REED (1912), (?)Llandoverian
strata (Mikkim Member) yielded Favosites sp. cf. F. forbesi?, Favosites sp. cf. F. niagarensis?, Lindstroemia sp.
and Calostylis dravidiana.
Based on the present study of coral material collected from the type section we can confirm occurrences
of following tabulate and rugose corals: Favosites spitiensis, Favosites sp., Plasmoporella sp., Halysites wallichi,
Halysites? sp., Protaraea? sp., Proheliotidae? gen. et sp. indet., Calostylis? sp., Streptelasma sp.,
Streptelasmatidae gen. et sp. indet. Of them, Favosites sp. and Plasmoporella sp. occurred in the unit P/13.
Streptelasma sp., Streptelasmatidae gen. et sp. indet. and Halysites? sp. were found in the units P/8, 10 and
16, respectively. Others were collected in the well weathered rubble just below the section that derived
from the Takche Member.
