Miocene bryozoans from the Indonesian Archipelago have been poorly investigated in the past. Several factors combine to explain their poor fossil record, including difficulties in locating good exposures in areas characterized by lush vegetation, dominance of inconspicuous encrusting species, and the adverse effects of diagenesis on fossil preservation. A large collection of samples from the Kutai Basin (East Kalimantan) made during the Marie Curie Initial Training Network ‘Throughflow’ has allowed new insights into the diversity of Miocene bryozoans in this region. The bryozoan assemblage as a whole consists of 123 species, which represents a remarkable increase in diversity compared to previous knowledge. Substrate availability appears to be the main factor controlling bryozoan distribution, the majority of encrusting species being associated with plate-like scleractinian corals. Collecting curves allow sampled sites to be divided into three groups characterized by high, medium and low species richness. The site of highest diversity is a mesophotic reef slope, environment influenced by strong input of terrigenous sediment. Ordination plots show no clear patterns of distribution among sites, with putatively endemic species accounting for most of the discrimination. A similar level of endemism and habitat heterogeneity characterizes modern, tropical bryozoan faunas. However, many more intermediate sites need to be sampled to achieve a fuller understanding of the true pattern of bryozoan species distribution in the Miocene of the Kutai Basin.

JF - Scripta Geologica Y1 - 2014 A1 - Emanuela Di Martino A1 - Paul D Taylor SP - 17 EP - 144 KW - BRYOZOA KW - East Kalimantan KW - INDONESIA KW - Miocene KW - TAXONOMY AB -The Cenozoic bryozoan fauna of Indonesia has been severely neglected in the past. In this pioneering study, based on new material collected during the two field seasons of the Throughflow project, we describe a total of 51 bryozoan species, comprising 15 cyclostomes and 36 anascan-grade cheilostomes, ranging in age from Early to Late Miocene (Late Burdigalian to Messinian), collected from 17 sections located in the vicinities of Samarinda, Bontang and Sangkulirang in East Kalimantan, Indonesian Borneo. Eleven of these species (Microeciella nadiae sp. nov., Pseudidmonea johnsoni sp. nov., Cranosina rubeni sp. nov., Parellisina mirellae sp. nov., Vincularia berningi sp. nov., Vincularia semarai sp. nov., Vincularia tjaki sp. nov., Vincularia manchanui sp. nov., ?Gontarella sendinoae sp. nov., Canda giorgioi sp. nov. and Canda federicae sp. nov.) are new. Ten species show affinities with Recent taxa from the Indo-Pacific. Bryozoans are found mainly encrusting the undersides of platy corals from low- and high-relief build-ups and coral carpets in mixed carbonate-siliciclastic environments.
VL - 146 ER - TY - Generic T1 - Why is the tropical Cenozoic fossil record so poor for bryozoans? T2 - 16th International Bryozoology Association Conference Y1 - 2013 A1 - Paul D Taylor A1 - Emanuela Di Martino KW - Bryozoans KW - Cenozoic KW - colony-forms KW - diagenesis KW - mineralogy AB -Diverse bryozoan assemblages have been recorded from widely across the Cenozoic palaeotropics, including the West Indies and Central America (Miocene-Pleistocene), Arabia (Oligocene), East Africa (Miocene), India (Eocene-Miocene) and the East Indies (Eocene-Miocene). However, records of Cenozoic tropical bryofaunas are relatively few compared with higher latitudes, and bryozoan limestones seem to be lacking. Insights into the reasons for this poor fossil record can be gleaned from comparisons with modern tropical bryozoan faunas, and consideration of the effects of diagenesis on fossil preservation and other factors that bias against the tropical Cenozoic fossil record. At least for the North Atlantic, bryozoan assemblage diversity in the modern tropics is not significantly less than in higher latitudes. However, a survey of colony-forms shows that encrusting species of small biomass are more dominant in tropical assemblages (mean 78% of species) than they are outside the tropics (mean 60% of species). These encrusting colonies may be difficult to observe and study when, as is often the case in tropical carbonate settings, diagenetic cement binds sediment firmly to the colony surfaces. Most erect bryozoan species living today in the tropics have weakly mineralized skeletons with a poor potential for fossilization; robust species capable of generating large quantities of carbonate sediment are uncommon. In addition, a higher proportion of cheilostomes in the tropics have metastable skeletons of aragonite: a Raman spectroscopic survey of 23 bryozoan species encrusting the undersides of platy corals from Puerto Rico and Malaysia showed 30% to be aragonitic and 27% bimineralic. Along with the typically higher Mg levels in the calcite of tropical cheilostomes, this further biases against preservation of bryozoans in the Cenozoic fossil record.

T2 - 16th International Bryozoology Association Conference Y1 - 2013 A1 - Emanuela Di Martino A1 - Paul D Taylor KW - Bryozoans KW - epiphytes KW - fossil KW - RECENT KW - seagrasses AB -Information concerning fossil and modern bryozoan assemblages reported from seagrass habitats is scattered through a large number of papers. The current paper groups taxonomically data from the literature on both modern and fossil bryozoans associated with seagrasses. Most of the modern data comes from studies focused on Posidonia oceanica meadows inhabiting the Mediterranean Sea, where a total of 152 bryozoan species have been recorded. Forty-one species have been reported on seagrasses from other geographical areas, such as Saudi Arabia, tropical America, Japan and Australia. Differences are outlined between the well-delineated communities of the leaves and the rhizomes, and some generalizations are made about morphological strategies for living as seagrass epiphytes. Seagrasses are seldom fossilized but examples of ancient communities can be inferred from the presence of bioimmurations of seagrass surfaces and from associated biota. They include a single Cretaceous community from the Maastrichtian of The Netherlands (43 bryozoan species), and a few Cenozoic communities described from several geographical regions (e.g. Europe, tropical America, Indo-Pacific; 72 species). New data is reported from a dark grey, silty clay in the Miocene of East Kalimantan (Indonesia) where the presence of the seagrass-indicative gastropod Smaragdia allows interpretation of the palaeoenvironment as a seagrass meadow with associated corals. The bryozoan assemblage here is monogeneric, comprising two species of Vincularia.

Johnson A1 - Willem Renema SP - 110 EP - 122 AB -Most studies of Cenozoic shallow-water, mixed carbonate-siliciclastic depositional systems have focused on their sedimentology. To date, however, comprehensive analyses of biotas and biofacies of Indo-West Pacific reefs that developed in mixed carbonate-siliciclastic systems are lacking. This study describes the palaeoenvironment and biodiversity of a late Burdigalian patch reef that developed in a mixed carbonate-siliciclastic depositional system. The studied exposure is located at the northeast margin of the Kutai Basin near Bontang (Indonesia), and is approximately 80 m wide and 25 m thick. Multi-taxon analysis of the most abundant fossil groups, including larger benthic foraminifera, corals, coralline algae, and bryozoans, aims to provide a model for environmental interpretation that will allow comparison with similar deposits of Indo-West Pacific region. Based on fossil content and lithology, five different facies types have been distinguished: foraminiferal packstone (FP), bioclastic packstone with foralgal communities (BP), thin-platy coral sheetstone (CS), platy-tabular coral platestone (CP), and shales (S). Among larger benthic foraminifera, smaller and more robust forms dominate in the FP and BP facies, while larger and flatter forms are the most abundant in the CS and CP facies. Thin-platy corals are dominant in the CS facies and gradually change into thicker platy-tabular forms in the CP facies. Assemblages and growth forms of coralline algae show no major differences between the facies types and are dominated by melobesioids and Sporolithon. The majority of bryozoan species are encrusting and were found only in the CS facies. Light-dependent organisms occurring in the reef indicate low light conditions typical for mesophotic reefs. The relatively small size of this reef complex and quite distinct vertical changes in the facies types, combined with the high siliciclastic content in most of the units, points to strong terrigenous input affecting water transparency as the main factor controlling the reef growth.
