It was found in marine sediments in the Alboran Sea during the Pleistocene. Septate, brown, around 32x15 micrometers, with perforations scattered across the surface, and two apical pori.
These bones come from a Pleistocene archaeological site located in Timor-Leste near Lake Ira Lalaro. Freshwater and marine fish remains have already been identified at this site. We have a few ideas that are not very conclusive. If you have any clues, don't hesitate. Thanks !

Along the North American Pacific Northwest and West Coasts, what is the strongest archaeological evidence for a late Pleistocene human colonization of the Americas from 14,000-13,000 cal BP?
I have a colleague that has ammassed impressive knowledge and collections of Pleistocene Bovivni from North America. Who can I put him in touch with to sample these 'sub-fossils'?
Dear all,
I am working on the biostratigraphy of Pleistocene sediments from the high latitude region in south-east Indian ocean sediments. Kindly suggest me any book or articles in which the above-mentioned foraminifera are discussed. The articles on the zonation will more be appreciated.
Thank You
I remember that one time I came across a publication, where a frequent occurrence of M1 with the supplementary loop was mentioned. It might have been the Holsteinian of Netherlands (not for sure). Now I need it, but I forgot whose the publication was

Hi I have a number of δ13C (from AMS dating) values for the same species of freshwater gastropods in Indonesia, that show different δ13C values in the Holocene and Pleistocene and I want to understand why this is happening. I have tried to research what can cause changes in δ13C but I am turning up results about human diets and differences between terrestrial, freshwater, and marine plants. I have come across nothing to explain why the values would be changing in one species over time.
The results are uncorrected samples dated c. 9-10,000 BP with δ13C = -11, while uncorrected Pleistocene samples dated to between c. 17-25,000 BP have δ13C = -6.
These values do not correlate with how I understood δ13C values to behave. If freshwater plants are meant to have a general value between -35 and -25 then shouldn't a gastropod that lives 100% in that environment have a similar δ13C? and shouldn't that be broadly stable over time too?
I would really appreciate if someone could point out the obvious thing I am missing or point me towards an explanation as I would really like to understand why I am seeing these different results.
Our study group is looking for a geochronological lab where to date Pleistocene (<1 Myr old) Alunite generated by hydrothermal alteration of volcanic systems. This mineralogical phase were identified by XRD at Azufre and Toconce volcanoes, northern Chile
Hello everyone. I am studying the shape changes among postcranial specimens of different Pleistocene large Bovids (Bison-Bos), and I need to analyse the (2-D) curve data that I have aquired in TPSdig2 across specific bone structures (e.g. ventral side of distal phalanx), of which some are very complex (e.g. distal end of metapodials etc). What procedure should I follow for the analysis? Can I use PAST or some other open software? Thank you for your time and consideration.
I'm interested in patterns of Palaeoenvironmental variability in the Senegal Valley during the Middle and Upper Pleistocene, particularly in the lower valley after the confluence with the Faleme River. However, I am having trouble finding modern sources of information, and many older sources are not available on-line. Can anyone help direct me to available/key resources that document patterns of environmental variability in the Senegal Valley?
Did they survive after the Eemian and for how long? The actual question would be if they were still around in the Brörup interstadial (MIS 5c) and how much the Brörup fauna differed from the Eemian one (MIS 5e)? Vice versa, when did the mammoth-dominated fauna first appear in Central Europe after the Eemian? In MIS 5b or earlier? Thanks in advance, Micha
I feel like there has to be a database, but I can"t seem to find it. Thanks for your suggestions. All the best, Micha
Please help me in the identification of this well preserved fossil plant found in Tufa . Thank you in advance !


Are you aware of publications describing subaerial accumulation of loesses and soil formation on Pleistocene glaciers (for example, Laurentide Ice Sheet, Fenno-Scandian ice sheet), above ice? Maybe within the marginal zones of glaciers?
I have long heard from a colleague that there is such an article, but I can not find it. It seems that this article says that loess deposits could have accumulated on the glacier. There were soils and plants on these loesses. Thanks to this, the giant flat glaciers were not deprived of life. An interesting hypothesis. I would really like to know the details. Maybe someone knows this articles?

There is only so much blood to be wrung from a stone. Projectile points and bifacial flaked stone technology, in general,
cannot by themselves elucidate the culture history of pioneering New World populations. Too little is knowable about behavior, society, and religion by reference to flaked stone artifacts only. In this nicely crafted paper the author pushes the limit about what can be learned from flaked stone points. Clearly, it is time to take a new tack -- to use other data sets to address questions that need answering.
Sites that can teach us about Clovis social behavior and ritual behavior exist. We do not have to belabor flaked stone artifacts. Proboscidean kill and butchery sites with organic preservation and an abundant record of Clovis behavior await reporting. Let us turn to them and give projectile points a rest!
I interested to comprehend the tectonic set up of Pleistocene terraces.
I am interested in any published data on how percentage of different age stages (juveniles, subadults ...) change depending on the type of the taphocoenoses etc?
I belong to a research team of archaeologists from the Univeristy of the Basque Country (UPV/EHU) that works in the Liberated Territories of the Sahrawi Arab Democratic Republic.
One of the aspects of our research focuses on the analysis of the palaeoenviroment in this region during the Pleistocene.
We've obtained some OSL samples from palaeodunes and we would like to know if someone knows a dating laboratory with experience in the analysis of this sort of environments or has worked with samples form the Sahara desert.
Thank you very much.

I have been searching for some articles which may address the problem mentioned above. I could find some excellent papers dealing with origin of red beds in sand dunes but hardly any dealing with fluvial deposits of Holocene or Late Pleistocene.
Any help in this regard is welcomed.
Dear Researchers
I have recently collected leptobos / its relatives from Pinjor Formation of Siwaliks; can we make comparative study?

This sand body is located on the southern edge of the Pannonian Basin, on the southern slopes of the Papuk Mountain, and the age is Pleistocene, approximately 1.6 million years. The sand is medium to coarse grained with 2-31% of gravel. It contains a lot of fossil remains (fish bones, dolphin bones) from a nearby older sediments (Pliocene and Badenian). No structures were found on site that would help us to determine sedimentary environment.
Could it be a quick slope movement of sediment triggered by earthquake?
We found these fossils on outcrop of Late Pleistocene deposits (clay) in southwestern coast of Novaya Zemlya archipelago (Yuzhny island, Moller bay). Also, this outcrop are rich for molluscs’ shells (genuses: Tridonta, Mya, Hiatella).

Pleistocene remains such as woolly mammoth bones have been found in some quarries in southern Indiana. Do these fossils in quarry settings indicate a high energy depositional environment, perhaps from glacial meltwater overland flow or floods of some sort? How many such finds exist from quarry locations? What is the range of such finds?
Hello! What could be a reason for disapperance of diatoms, when sponge spicules are still present, as they are from the same material SiO2?
Thanks in advance

I am working on the fossils of holocene sediments in bengal basin.
I've attached a pdf with 4 ostracod photos. The sample comes from an "ostracod ironstone", thought to be Early Paleozoic, Mackenzie Mountains, western Northwest Territories Canada. The nesting is the curiosity. Thanks.
I am interested in whether or not there is any evidence of historical distributions of extant seabird groups in the North, particularly in relation to glacial recession, but have not been able to locate any specific sources for this information.
I am working on population genetics of typical wetland species in the northeast Germany.
There are a lot of wide ranges of Arc-collision stage age and Gondwana collision age!!
I see different approximate timings of the Palaeocene-Eocene Thermal Maximum (ranging 56-55 Ma) in the literature.What is the most accurate internationally accepted timing and duration of PETM?
I'm searching for rodents and insectivores in the Pliocene of Belgium. There only seem to be records from the Paleogene and Pleistocene
Actually I am thinking about the mode of formation of Pleistocene red clay in Bangladesh.
Dear all, I have some marine gastropod fossils from Sangiran Central Java Indonesia which more than 75% of the collection were found in Recent/Quarter period; the sediment was classified as Pleistocene. I wonder if somebody here could suggest me please on where and how much the cost to radio-date their geological age, perhaps their 87Sr/86Sr ration or else? as I am not at all familiar in that field. Cheers.
Elphidium gunteri has been identified in Plio-Pleistocene sediments in the Salton Basin. I'm attempting to determine whether or not this species arrived via a marine incursion from the Gulf of California. (The other possibility is avian transport.)
I would like to know whether any individual belonging to any extinct or extant bird species is conserved in any museum or other place worldwide. Would like to know about genetic studies on this material.

The clay assemblage in Qaidam basin is mainly composed by illite, chlorite and smectite (including mixed layer minerals) with low content of kaolinite since Pleistocene. While the abonormally high content of smectite occured in core clay-rich sediments at ~12ka, and the thickness of the core sediments is about 50 cm. The lithofacies features of the core is mainly composed by the lower part (below ~50m in depth) of clay and dark peat and the upper part of halite, halite with silt and silty clay.
I need the refference points for "post-holes looking" features in the Nile Valley
Hi, molecular clock rates are widely used to link genetic divergence in invertebrates to vicariance; for example, geological events in the Pleistocene, or earlier in the Miocene. My question is how far back in time is appropriate for (invertebrate) mtCOI dating analysis? Is the Mesozoic too far back in time? (btw, I realise the use of mtCOI molecular clock rates are controversial)
I would like to get age constraints on the deposition of fluvial sediments in a river deposit in the Kenya Rift. Age estimates are Mid to Late Pleistocene. The sources are mostly basaltic, trachytic and phonolitic lava flows. Quarz content is fairly low, so I'm guessing OSL won't be the method of choice. Any ideas?
I have read about several hypothesis to explain the development of agriculture in many parts of the world by the end and soon after the Pleistocene. Does anyone tested/studied the following: the over-hunting of megafauna resulted in ephemeral and localized food surpluses and, soon after, population pressure, which by their turn leaded to the experimentation with wild plants and more investment of time in cultivation resulting in the development of agriculture?
Trying to track down any mention of ground bone points from LSA East African contexts without much luck!
Now I'm working on with fossil fish remains of the genus Esox (Esocidae) from the heterochronous strata of Southeastern Europe in the range of Late Miocene - Pleistocene. Infomation about the qualitative and quantitative composition of the extinct pikes is very important for me. How many species are described? Which of them are valid? I will be very thankful for the correct information on this topic!
We found a well preserved fossil fish in older Pleistocene lacustrine sediments composed of clastic varves. If there is anyone who can help, please, contact me !
We are looking for a multidisciplinary team to carry out geological, chronological and environmental studies on stratigraphical sequences reaching at least 20 m deep. Our initial evaluations suggest that the deposits may present a continuous chronostratigraphical sequence dating from around 1.5 Myrs. The two volcanic structures are in a closed depression context linked to soil subsidence at the base of their lava emission centers. This situation is due either to the collapse of the craters under the weight of the lava or to the retraction of the lava during its cooling phase. These depression structures functioned as sediment traps which have yielded archaeological surface remains attributable to the Middle Pleistocene and through to the Holocene. They are located in the south of France, in the Baumes volcanic complex (communes of Caux, Nizas, Pézenas, Lezignan-la-Cebe ...). Exceptional sediment traps, the exhaustive study of these infillings would be a major asset for the paleoenvironmental restitution of the sector and more broadly of Western Europe since 1.5 Ma.
Please contact me if you are interested and I will be able to provide you with more information.
Je cherche une équipe pluri-disciplinaire pour l'étude géologique, chronologique et environnementale sur des séquences stratigraphiques de minimum 20 m de profondeur susceptibles de recouvrir une chronologie continue depuis 1,5 Ma. Il s'agit de deux structures volcaniques en dépression fermées dues à l’affaissement de sol à l’aplomb de centres d’émission de lave soit liées à un effondrement des structures du cratère sous le poids de la lave soit à la rétractation de la matière lors du refroidissement de la lave. Ces structures dépressionnaires ont fonctionné comme des pièges sédimentaires et livrent des éléments archéologiques en surface depuis le pléistocène moyen jusqu’à l’holocène. Elles sont localisées dans le sud de la France, dans le complexe volcanique des Baumes (communes de Caux, Nizas, Pézenas, Lézignan-La-Cèbe ...). Pièges sédimentaires exceptionnels, l’étude exhaustive de leur remplissage serait un atout majeur pour la restitution paléo-environnementale de ce secteur et plus largement de l’Europe de l’ouest depuis 1.5 Ma.
Merci de me contacter pour de plus amples renseignements.
I want to study the formation process of freshwater icthyofauna on the south of Eastern Europe during the Late Cenozoic. First of all, I want to learn how it is possible to extract DNA of extant bony fishes, and after that - start to extract DNA of the Late Pleistocene and Holocene samples. How can I do this? I will be very thankful to everyone for the comments and advice on methodology.
The two atlases from Late Pleistocene gravel deposits of the Magdeburg region, northern Germany, have been assigned to the auerochs (Bos primigenius) but look quite different. Are there any criteria to rule out that one of them actually belonged to the steppe bison (Bison priscus)?
The order in which teeth are replaced may give information on phylogeny and life-history variables (Schultz's Rule), but also environment. Specifically, it might show whether the permanent premolars erupted before the M1 erupted or is in wear is important.
Looking at a collection of molars from Middle Pleistocene (Saalian) to Late Pleistocene (Weichselian) gravel pits of northern Germany, I found some that are clearly distinct from the usual Mammuthus primigenius teeth, especially in their somewhat larger width of enamel lamellae (around 1.8 cm). Do these rather represent the steppe mammoth (M. trogontherii) or the straight-tusked elephant (E. antiquus)? Distinction criteria?
I'm looking for the paper of Matsumoto (1924) in which the genus was established, the paper in which Palaeoloxodon raised up to rank of genus e and so on. Can you help me?
Especially Betula, Pinus, Corylus, Quercus, Tilia, Ulmus, Alnus, Carpinus, Fagus. From where did each of them come when they successively reappear in the Holocene pollen records of Middle Europe?
From Iberia? Italy? The balkans? Anatolia? The levante? The Mediterranean region in general? East Europe? Central Asia? What is known about their refugia during the Last Glacial Maximum and migration paths thereafter?
