horizon. Oxycerites cf. orbis (Giebel) is a<br />
zonal index of the Late Bathonian in other<br />
areas and thus facilitates interprovincial correlation.<br />
Besides, palaeobiogeographic and<br />
stratigraphic distribution of many species have<br />
been modified based on new information. For<br />
example, macrocephalitin species, i.e., Kamptokephalites<br />
cf. etheridgei Spath (1928), Macrocephalites<br />
bifurcatus transient intermedius<br />
Spath (1928), M. cf. mantataranus Boehm<br />
(1912) were previously known from West Pacific,<br />
Indonesia have been now found in Kutch.<br />
Gracilisphinctes Buckman (1920) has been<br />
previously known to occur during the Middle<br />
Bathonian time, the present work extends its<br />
stratigraphic distribution up to the definite<br />
Upper Bathonian horizon. Procerites hians<br />
(Waagen) an endemic species in Kutch previously<br />
known from the Upper Bathonian beds,<br />
its stratigraphic range has been extended down<br />
to the Middle Bathonian. Detail taxonomy of<br />
the newly obtained taxa has been done and in<br />
many cases sexual dimorphism has been recognized.<br />

Obornella Cox 1959, is an extremely depressed<br />
genus of the family Pleurotomariidae.<br />
It first appeared during Toarcian in France and<br />
continued up to the Tithonian. Obornella is a<br />
Tethyan genus restricted only to western<br />
Europe except previous reports of migration<br />
of a species to Kutch during the Late Bathonian.<br />
The present find describes a new species<br />
of Obornella, i.e., Obornella lakhaparensis<br />
from immediately below the Jurassic–<br />
Cretaceous boundary in Kutch. The present<br />
species is quite distinct from other Obornella<br />
species and has many novelties. A detailed<br />
systematic description is provided.<br />

The new epi-byssate bivalve Parapergamidia<br />
changtaiensis gen. et sp. nov. of the<br />
family Pergamidiidae occurs in the Upper Triassic<br />
( Late Carnian–Early Norian) Tumugou<br />
Formation of the Changtai-Gacun area, eastern<br />
Qinghai-Xizang Plateau, China. During<br />
the Late Triassic, this area was an intra-arc rift<br />
of the Yidun Island Arc along the eastern<br />
margin of the Tethyan seaway. The new taxon<br />
has a big byssal gape, prominent byssal retractor<br />
muscle scars, and anteriorly oblique and<br />
posteriorly to posteroventrally elongated<br />
shape. The thin shell is distinctly longer than<br />
high.<br />

Fragmentarily preserved shells – mainly<br />
pro-ostraca, in several cases also phragmocones<br />
– occurring together with arm hooks<br />
and the ink sac of the Carnian (Late Triassic)<br />
coleoid cephalopod Phragmoteuthis bisinuata<br />
(Bronn) from Lunz (Austria) are examined<br />
with the scanning electron microscope and<br />
energy-dispersive spectrometer. The proostracum<br />
bears black, shiny, pitch-like sheets.<br />
The black sheets, the ink sac content and the<br />
arm hooks have a granular ultrastructure of<br />
0.1–1 μm grain size. The arm hooks and black<br />
sheets are micro-laminated; each lamina consists<br />
of fibres. The ink consists of an agglomerate<br />
of grains. On the ventral (internal) side<br />
of the pro-ostracum, the black sheets occasionally<br />
bear agglomerates of homogeneous,<br />
ink-like material along with heterogeneous<br />
structures. The pro-ostracum has crystalshaped<br />
units with lamello-columnar ultrastructure<br />
of the inner layer and plate ultrastructure<br />
of the outer layer. This resembles the Late<br />
Triassic Lunzoteuthis [Doguzhaeva, L.A.,<br />
