017510   Lokho K;Raju D S N (NO, Wadia Institute of Himalayan Geology, 33 GMS Road, Dehradun-248 001, Email: kapesa@wihg.res.in) : Langhian (early middle miocene) foraminiferal assemblage from Bhubhan formation, Mizoram, NE India. J Geol Soc India 2007, 70(6), 933-8.

Small but varied assemblage of planktonic and benthic foraminifers comprising at least six genera and seven species is documented from the Upper Bhubhan Formation exposed at Thuampui in Aizawl District of Mizoram (NE India). The fossils from Thuampui are generally poorly preserved and some are even deformed, nevertheless they are important for determination of age and paleobathymetry. Based on this foraminiferal assemblage an early Middle Miocene age equivalent to planktonic foraminiferal zones N8-N9 and a paleobathymetry of 50 m is suggested for the fossiliferous Upper Bhubhan Formation at Thuampui of Mizoram.

008286   Kumar S;Pandey S K (Centre of Advanced Study in Geology, Lucknow Univ, Lucknow-226 007, Email: surendra100@hotmail.com ) : Discovery of trilobite trace fossils from the Nagaur Sandstone, the Marwar supergroup, Dulmera area, Bikaner district, Rajasthan. Curr Sci 2008, 94(8), 1081-5.

Well-preserved trace fossils produced by trilobites are reported from the upper part of the Nagaur Sandstone of the Nagaur Group, the youngest group of the Marwar Supergroup (Trans-Aravalli Vindhyans). The trace fossils are preserved as epirelief on the sole of the silty shale beds. The trace fossils are Cruziana isp., Dimorphichnus isp., Rusophycus isp. and Aulichnites isp. Except Aulichnites, the trace fossils are known to have been produced by trilobites. Indication of the presence of trilobites in the Nagaur Sandstone gives the trace fossil-bearing horizon a Lower Cambrian age. Thus the present finding supports a Lower Cambrian age to the upper part of the Marwar Supergroup.

A small collection of fossil pteropods, including some unidentified species, provisionally referable to the families Limacinidae, Creseidae, and Clioidae (?) is reported from the late Middle Eocene-Late Eocene beds of the Upper Disang Formation exposed near the town of Pfutsero, Phek District, South Central Nagaland (Assam-Arakan Basin, northeastern India). This is the first record of fossil pteropods from this part of India. Although based exclusively on juvenile or incompletely preserved adult shells, documentation of this collection is important from the viewpoint of biostratigraphy as well as palaeoecology. The occurrence of pteropods in the Upper Disang Formation indicates deposition in an open marine basin above the aragonite compensation depth. The combined assemblages of pteropods and previously reported uvigerinid foraminifers from the Upper Disang Formation indicate a palaeobathyªmetry of -500 m, i.e. upper bathyal zone, and a tropical-subtropical climate.

A well-laminated, cross-bedded and coarse to very coarse-grained calcareous (beach rock) sandstone unit is exposed on either sides of Mandapam foreland along the Palk Bay and the Gulf of Mannar coasts at about 2 m asl. Presence of abundant coral debris and pelecypod shells in the sandstone indicates its formation under high-energy beach facies. Coral debris Acropora sp. and pelecypod shells, Arca sp. in living positions collected from the sandstone unit yielded 14C ages of 6110 and 5650 yrs BP respectively. The level of occurrence of calcareous sandstone and ^{14C ages of coral debris and pelecypod shells confirm that the mid-Holocene high strand line stood at about 2 m asl in this coastal segment between 5650 and 6110 yrs BP.}

Curr Sci 2008, 94(6), 758-64.

Stilostomella lepidula (Schwager), an infaunal benthic foraminifer, is an important component of the deepsea environment, showing wide geographical distribution and variation in test morphology. The ecological preference and timing of its disappearance across the mid-Pleistocene Transition (MPT) is widely debated. To understand the ecological preference, and timing and cause(s) of disappearance of S. lepidula, we analysed Neogene record of this taxon from Ocean Drilling Programme and Deep Sea Drilling Project sites located at bathyal to abyssal depths in the Atlantic and Indian oceans. Population plots of this species at various sites reveal that this taxon showed a substantial increase during the warm late Oligocene to the middle Miocene and suffered a major decline across the middle Miocene cooling event (15-13 Myr). S. lepidula disappeared at -0.6 Myr very close to the MPT (0.9-0.8 Myr) from the Indian and Atlantic oceans, coinciding with a change from a 40 to 100 Myr world with amplified ice-age cycles. Suggests that high-amplitude glacial cycles, frigid deep-water temperatures and strong circulation drove S. lepidula to nearly disappear across the MPT.

Leaf impressions from the Late Tertiary sediments of the Mahuadanr valley, Jharkhand have been studied morphotaxonomically. The qualitative and quantitative methods of comparison of morphological features between the fossil and extant taxa revealed the occurrence of sonic more taxa representing 12 species of 10 dicotyledonous families. On the basis of present assemblage as well as previously published data, the palaeoclimate and phytogeography ot the Mahuadanr area during the late Tertiary have been deduced.The analysis of present distribution of all the modern comparable species of the fossils indicates that most of the taxa presently grow in the mixed deciduous forests of the Himalayan foothills, central India, south India and adjoining area of the Mahuadanr valley, which suggests that mixed deciduous type of forest flourished in and around the fossil locality during sedimentation. The presence of a good amount of recovered taxa growing today in the vicinity of the Mahuadanr fossil locality indicates that same flora is persisting, suggesting that there was not much climatic change in the area since the late Tertiary time.

Littoral sediments of Dwarka beach, Gujarat yield a Recent foraminifcral assemblage comprising 26 species dominated by the family Hauerinidae (42.3%). Systematics and distribution of the constituent species are discussed. The Dwarka beach foraminiferal assemblage is a typical shallow, warm-water assemblage dominated by calcareous forms. Six species, viz., Texlularia aff. T. kerimbaensis, Textularia cf. T. punjabensis, T. rugosa, Quinqueloculina aff. Q. oculus, Triloculina aff. T. inornata, and T. aff. T. unidentata are recorded for the first time from the Indian waters, while two species, viz., Quinqueloculina sulcata and Amphistegina madagascariensis are recorded for the first time from beach sediments of the West Coast of India. The Dwarka foraminiferal assemblage is compared with other foraminiferal assemblages of the West and East coasts of India. The study indicates that West Coast of India has a prolific foraminiferal assemblage with high Total Species Number (TSN) as compared to the East Coast. The Dwarka beach is a relatively clean beach with coastal waters free from marine pollutants as reflected by the absence of any distortion and abnormality in the foraminiferal tests. Furthermore, salinity appears to play a dominant role among various ecological factors controlling the distribution of foraminifera along Dwarka coast.

Scanning Electron Microscopy of fossil leaf surfaces imprinted on amber nodules illustrate the potential of this technique in understanding the fine resolution details at the cell level including the density distributions of stomata and trichomes. Isolated trichomes are commonly found in certain ambers but are here described in a spatial cuticular context. Stomatal distribution and density are also recorded. About 15 fragments of an unidentified fossil leaf from the Vastan Lignite Mine, near Surat were studied and provide morpho-structural details of the cuticular surface, mode of preservation and an interpretation of palaeoecological conditions and depositional palaeoenvironments. Using multi-imaging techniques it has been possible to obtain three-dimensional images of body fossils as well as surface impressions of plant and insect remains from the same material.

The columnar stromatolite group Mistassinia Hofmann is described from the Fawn Limestone of the Keinjua Formation from Pataudh Hill near Chopan. The form is characterized by bipartite organization and bimodal development of laminae. It is made up of vertically accreting laminae in the central part of the column, and a secondary mode of asymmetrical, steeply inclined, obliquely accreting marginal laminae forming a partial or complete encrustation on the primary central portion. All three known occurrences of this form, including the present one, are from the Palaeoproterozoic and hence it is suggested that the form can be considered as an important form of this era and can be useful both for intrabasinal and interbasinal correlation.

The carbonate environment that developed during the Palaeocene in the study area is well represented in the three units of the Ninniyur Formation. The environment ranged from the shallow inner-ramp to mid- to uppermost outer-ramp environment and was host to several groups of invertebrate and foraminiferal fauna and algal flora. In the studied profiles of the lower, middle and upper units of this formation, it appears that it is the inner-ramp environment and its low-diversity assemblage of fossil forms that persisted throughout the course of deposition. The assemblage consists of foraminifers, represented by miliolids and fewer members of rotaliid and agglutinated groups, and calcareous algae (dasyclads). As this environment had a small habitat-area (ecospace) with limited possibilities of further evolutionary differentiation, it was marked by the persistence of low-diversity biota throughout the Ninniyur succession. However, this continuum was broken when the deposition of the middle unit occurred in deeper mid- to uppermost outer-ramp locations of sea in the Periyakurichchi area. This change resulted in an enlarged habitat-area allowing for multiplication of microhabitats to give rise to high-diversity coralline algal assemblage with some planktic species.

A systematic study of Recent benthic Ostracoda of southwest coast of India was made, based on 28 beach samples and 48 grab samples collected from the inner-shelf off the Malabar coast, Kerala. Samples were collected from Kumbla in the north and Mahe in the south of the coast and these were subjected to standard micropalcontological techniques. A total of 61 species belonging to 48 genera, 20 families, 3 superfamilies and 2 suborders of the order Podocopida were identified and reported with SEM photomicrography. Among these, Cytherella semitalis, Cytherelloidea leroyi and Keijcyoidea praecipua belong to Platycopa and remaining species belong to Podocopa. Leptocythere pulchra is recorded for the first time from the Indian waters. Hemitrachyleberis siddiquii and Neocytheromorpha reticulata are recorded for the first time from the west coast of India. The ostracod fauna of the study area shows close similarity with the ostracod assemblage of the Indo-Pacific region. A relatively slow rate of sedimentation is observed in the inner shelf, based on the carapace-valve ratio.
