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 />

207-212<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 />
