Abstract The collection and dissemination of vertebrate ichnological data is struggling to keep up with techniques that are becoming commonplace in the wider palaeontological field. A standard protocol required ensure recorded, presented archived a manner will be useful both contemporary researchers, future generations. Primarily, our aim make 3D capture practice, provide guidance on how such can communicated effectively (both via literature other means) openly perpetuity. We recommend data,...
Early footsteps in the Americas Despite a plethora of archaeological research over past century, timing human migration into is still far from resolved. In study exposed outcrops Lake Otero White Sands National Park New Mexico, Bennett et al . reveal numerous footprints dating to about 23,000 21,000 years ago. These finds indicate presence humans North America for approximately two millennia during Last Glacial Maximum south migratory barrier created by ice sheets north. This coincided with...
Hominin footprints offer evidence about gait and foot shape, but their scarcity, combined with an inadequate hominin fossil record, hampers research on the evolution of human gait. Here, we report in two sedimentary layers dated at 1.51 to 1.53 million years ago (Ma) Ileret, Kenya, providing oldest essentially modern human-like anatomy, a relatively adducted hallux, medial longitudinal arch, weight transfer before push-off. The size Ileret is consistent stature body mass estimates for Homo...
It is commonly held that the major functional features of human foot (e.g. a longitudinal medial arch, lateral to force transfer and hallucal (big-toe) push-off) appear only in last 2 Myr, but interpretations footbones footprints early ancestors (hominins) prior million years ago (Mya) remain contradictory. Pixel-wise topographical statistical analysis Laetoli footprint morphology, compared with results from experimental studies formation; foot-pressure measurements bipedalism humans...
Broadening access to both computational and educational resources is critical diffusing machine learning (ML) innovation. However, today, most ML experts are siloed in a few countries organizations. In this article, we describe our pedagogical approach increasing applied through massive open online course (MOOC) on Tiny Machine Learning (TinyML). We suggest that TinyML, resource-constrained embedded devices, an attractive means widen because TinyML leverages low-cost globally accessible...
Human footprints at White Sands National Park, New Mexico, USA, reportedly date to between ~23,000 and 21,000 years ago according radiocarbon dating of seeds from the aquatic plant Ruppia cirrhosa. These ages remain controversial because potential old carbon reservoir effects that could compromise their accuracy. We present new calibrated 14C terrestrial pollen collected same stratigraphic horizons as those seeds, along with optically stimulated luminescence sediments within human...
Abstract Modes of debris entrainment and subsequent transfer in seven “normal” five surge-type glaciers Svalbard (76–79 ° N) are outlined the context structural evolution a glacier as ice deforms during flow. Three main modes inferred from sedimentological observations: (i) The incorporation angular rockfall material within stratified sequence snow/firn/superimposed ice. This takes an englacial path through glacier, becoming folded. At margins at boundaries flow units including is strongly...
Irregular mounds of glacial debris, commonly referred to as 'hummocky moraine', until recently were linked ice stagnation during rapid climatic amelioration. However, recent work in Scotland has demonstrated that some hummocky moraine, dating from the Younger Dryas event ( c. 10 000 years BP ), was product deposition at active margins. Observations modern high–arctic glacier margins Svalbard (76–80°N) indicate moraines this type form under a dynamic glaciological regime, mainly by thrusting...
Glacial inversion modelling of continental-scale palaeo-ice sheets is now recognized as an important tool in palaeoglaciology. Existing palaeoglaciological reconstructions the dimensions, geometry and dynamics former ice are based mainly on glacial depositional, opposed to erosional, landforms. Part reason for this a lack detailed understanding origin significance erosional Here we review recent developments our processes landforms erosion consider their value involves removal transport...
Fossil evidence for longitudinal arches in the foot is frequently used to constrain origins of terrestrial bipedality human ancestors. This approach rests on prevailing concept that feet are unique functioning with a relatively stiff lateral mid-foot, lacking significant flexion and high plantar pressures present non-human apes. paradigm has stood more than 70 years but yet be tested objectively quantitative data. Herein, we show pressure records elevated mid-foot occur healthy, habitually...
ABSTRACT We report a Holocene human and animal footprint site from the Namib Sand Sea, south of Walvis Bay, Namibia. Using these data, we explore intratrail variability associated with small variations in substrate properties using “whole foot” analytical technique developed for studies ichnology. demonstrate high levels as result grain size, depositional moisture content, degree sediment disturbance, all which determine bearing capacity substrate. The two principal trails were examined, had...
Footprints are the most direct source of evidence about locomotor biomechanics in extinct vertebrates. One principal suppositions underpinning biomechanical inferences is that footprint geometry correlates with dynamic foot pressure, which, turn, linked overall limb motion trackmaker. In this study, we perform first quantitative test long-standing assumption, using topological statistical analysis plantar pressures and experimental computer-simulated footprints. footprints, relative...
Abstract We report the occurrence at 0.7 million years (Ma) of an ichnological assemblage Gombore II-2, which is one several archaeological sites Melka Kunture in upper Awash Valley Ethiopia, 2000 m asl. Adults and children potentially as young 12 months old left tracks a silty substrate on shore body water where ungulates, well other mammals birds, congregated. Furthermore, same layers contain rich palaeontological record, confirming that knapping was taking place situ stone tools were used...
Water is a fundamental resource, yet its spatiotemporal availability in East Africa poorly understood. This the area where most hominin first occurrences are located, and consequently potential role of water evolution dispersal remains unresolved. Here, we show that hundreds springs currently distributed across could function as persistent groundwater hydro-refugia through orbital-scale climate cycles. Groundwater buffers variability according to spatially variable response times determined...
Abstract When viewed from the air, Scottish ‘hummocky moraine’ can be resolved into a series of linear ridges that resemble those found at margins actively retreating glaciers today. Recent work has supported interpretation these as ice‐marginal landforms and authors believe majority deposits interpreted in this way. Consequently pattern deglaciation established fairly precisely ridges. This approach is applied to northern part Loch Lomond Stadial ice‐field order reconstruct regional...
The interpretation of glacigenic diamictons is a subjective process, for which quantitative support frequently sought from parameters such as clast shape and fabric. It has been widely suggested that different diamicton facies possess distinct clast-fabric signatures. This paper examines this concept using data set 111 fabrics, synthesis published results. Eigenvalues are calculated compared variety sedimentary facies. concluded fabric alone not able to discriminate between facies, it argued...
Abstract The aim of this paper is to demonstrate that much the ‘hummocky moraine’ present within northern part LochLomond Readvance ice cap formerly situated in North West Scottish Highlands may be interpreted as suites ice-front moraines deposited during active decay. These landforms can used reconstruct decay, whichleads important insights into shrinking form and associated environmental conditions. Evidence has been collected from 10803 airphotographs detailed field survey. It presented...
The Laetoli site (Tanzania) contains the oldest known hominin footprints, and their interpretation remains open to debate, despite over 35 years of research. two trackways present are parallel one another, which is a composite formed by at least individuals walking in single file. Most researchers have focused on single, clearly discernible G1 trackway while G2/3 has been largely dismissed due its nature. Here we report use new technique that allows us decouple G2 G3 tracks for first time....
