Toba Caldera

Acheulean artefacts are widely known from archaeological complexes in India and commonly comprise handaxes, picks and cleavers. These provide information on human occupation and evolution across India, and have been the subject of much research on stone technology. In some of these sites, artefacts are associated with a Pleistocene volcanic ash layer derived from the Toba caldera in Sumatra, but various studies have derived a wide range of ages from this deposit leading to differing schools of thought as to the age of the tephra. Recent trace element, fission track and mineralogical studies (since 2011), have enabled accurate recognition of each Toba eruptive unit across their fall out, but these approaches continue to be overlooked in some studies where artefacts and Toba tephra co-exist in India. This leads to significant errors in tephra identification, and thus hampers any derived age interpretations. Most recently, this includes the study by Deo et al. (2021) who, in Geological Society Special Publication 515 (Tiwari et al., 2021), report ages for artefacts and tephra from two sites in the Deccan Volcanic Province which have become pivotal in many arguments, namely Morgaon and Bori. Here we address these issues and reiterate the methods for identification of the three main Toba tephra deposits.

AbstractThe two Early Acheulian sites of Bori and Morgaon from the Deccan Volcanic Province in Upland Maharashtra, India bear some association with an acidic tephra deposit in a fluvial context. Acheulian artefacts in association with tephra were first reported in India from the site of Bori and numerous efforts to date this tephra have since been undertaken. These efforts employed various dating methods and produced a total of 10 absolute dates ranging from the Early Pleistocene with a maximum age of 1.4 ma to the Late Pleistocene with a minimum age of 23.4 ± 2.4 ka. However, field observations and a typo-technological analysis strongly suggests that these Early Acheulian artefacts occur in a semi-primary context and thus contest the Late Pleistocene age of the tephra and re-deposition of the artefacts as argued by some scholars.At Morgaon, the Acheulian artefacts have been recovered from basal fluvial sediments that contain clasts of laterite. These sediments are capped by two low energy clay facies that are separated by a high energy gravel lense. The tephra at Morgaon has been reported from the upper clay facies and has produced absolute dates ranging from the Matuyama period (> 0.78 ma) to the Late Pleistocene (41 ka).After more than two decades of investigation at these sites, the number of absolute dates procured through methods such as ESR, 39Ar-40Ar, U-Th and Palaeo-magnetism though encouraging, are inconclusive. The present communication is therefore an attempt to gauge the nature of palaeo-landscapes that most probably existed during the Early Quaternary. This will be achieved by studying local geomorphological variability between the two sites along with a preliminary analysis of lithic morphology.

Faunal Diversity

Abstract The Deccan Traps of peninsular India, representing one of the largest flood basalt eruptions on the earth's surface, have been a subject of intensive research in the last three decades because of the attributed link between the Deccan Traps and the Cretaceous-Tertiary boundary mass extinctions. In this context, the biota from the sedimentary beds intercalated with the volcanic flows and underlying the oldest volcanic flow are more important for understanding the faunal diversity and palaeobiogeography of India during the time span of volcanic eruptions. A detailed review of the vertebrate faunal diversity of the Deccan volcanic province is presented here.

We acknowledge with gratitude the comments by Pearce et al on our paper on the Acheulian and Tephra in the Deccan Volcanic Province in Peninsula India with reference to the sites of Bori and Morgaon. These comments are appreciated, and have been duly taken under advisement.

Legal Understanding

The purpose of the article is to typologize terminological definitions of security, to find out the general, to identify the originality of their interpretations depending on the subject of legal regulation. The methodological basis of the study is the methods that made it possible to obtain valid conclusions, in particular, the method of comparison, through which it became possible to correlate different interpretations of the term "security"; method of hermeneutics, which allowed to elaborate texts of normative legal acts of Ukraine, method of typologization, which made it possible to create typologization groups of variants of understanding of the term "security". Scientific novelty. The article analyzes the understanding of the term "security" in various regulatory acts in force in Ukraine. Typological groups were understood to understand the term "security". Conclusions. The analysis of the legal material makes it possible to confirm that the issues of security are within the scope of both legislative regulation and various specialized by-laws. However, today there is no single conception on how to interpret security terminology. This is due both to the wide range of social relations that are the subject of legal regulation and to the relativity of the notion of security itself and the lack of coherence of views on its definition in legal acts and in the scientific literature. The multiplicity of definitions is explained by combinations of material and procedural understanding, static - dynamic, and conditioned by the peculiarities of a particular branch of legal regulation, limited ability to use methods of one or another branch, the inter-branch nature of some variations of security, etc. Separation, common and different in the definition of "security" can be used to further standardize, in fact, the regulatory legal understanding of security to more effectively implement the legal regulation of the security direction.

Literature written in England between about 500 and 1100 CE attests to a wide range of traditions, although it is clear that Christian sources were the most influential. Biblical apocrypha feature prominently across this corpus of literature, as early English authors clearly relied on a range of extra-biblical texts and traditions related to works under the umbrella of what have been called “Old Testament Pseudepigrapha” and “New Testament/Christian Apocrypha." While scholars of pseudepigrapha and apocrypha have long trained their eyes upon literature from the first few centuries of early Judaism and early Christianity, the medieval period has much to offer. This article presents a survey of significant developments and key threads in the history of scholarship on apocrypha in early medieval England. My purpose is not to offer a comprehensive bibliography, but to highlight major studies that have focused on the transmission of specific apocrypha, contributed to knowledge about medieval uses of apocrypha, and shaped the field from the nineteenth century up to the present. Bringing together major publications on the subject presents a striking picture of the state of the field as well as future directions.
