Este trabalho descreve marcas encontradas em fósseis de mamíferos pleistocênicos do Sítio Lagoa da Pedra, que fica localizado no distrito de Conceição das Creoulas, identificando possíveis relações temporais e/ou físicas entre os grupos pré-históricos e a megafauna que coabitou a região nordeste do Brasil, em Salgueiro - PE, no Pleistoceno Final - Holoceno Inicial. A metodologia aplicada, utilizando microscópio estereoscópico, identificou fósseis que apresentam marcas que foram possivelmente causadas por instrumentos líticos. O trabalho apresenta indícios de interação homem-megafauna através da caça desses animais, reforçando evidências já existentes sobre a coabitação durante o final do Pleistoceno e início do Holoceno.BRANDS ON MEGAFAUNA FOSSILS IN LAGOA DA PEDRA, SALGUEIRO-PE, BRAZIL ABSTRACTThis work describes marks found on fossil mammals of the Pleistocene Lagoa da Pedra Site, which is located in the Conceição das Creoulas district, identifying possible temporal and / or physical relationships between prehistoric groups and the megafauna that cohabitated the northeast region of Brazil. , in Salgueiro - PE, in the Late Pleistocene - Early Holocene. The applied methodology, using stereoscopic microscope, identified fossils presenting marks that were possibly caused by lithic instruments. This work presents evidence of human-megafauna interaction through hunting of these animals, reinforcing existing evidence on cohabitation during the late Pleistocene and early Holocene.Keywords: Quaternary; marks; fossils; pleistocene mammals; megamammals.

Pleistocene Mammals

Late Pleistocene fossils have been recovered sporadically in the Edmonton area, in central Alberta, for many years but there has been little work in determining their age. Fossils from quarries in North Saskatchewan River terraces and buried valley gravels are recognized as Late Pleistocene (mid-Wisconsinan) and early Holocene taxa, and numerous 14C dates on mammalian remains now support the assessment. The mammalian fauna consists of at least 16 taxa, including mostly grazing herbivores, but also three carnivores: Canis cf. Canis lupus (gray wolf), Arctodus simus (giant short-faced bear), and Panthera leo atrox (Pleistocene lion). The carnivores are first records for the region, and Arctodus is a first record for Alberta.

Abstract A multiproxy record from Twin Ponds, VT, is used to reconstruct climatic variability during the late Pleistocene to early Holocene transition. Pollen, ostracodes, δ18O, and lithologic records from 13.5 to 9.0 cal ka BP are presented. Pollen- and ostracode-inferred climatic reconstructions are based on individual species’ environmental preferences and the modern analog technique. Principal components analysis of all proxies highlights the overall warming trend and centennial-scale climatic variability. During the Younger Dryas cooling event (YD), multiple proxies show evidence for cold winter conditions and increasing seasonality after 12.5 cal ka BP. The early Holocene shows an initial phase of rapid warming with a brief cold interval at 11.5 cal ka BP, followed by a more gradual warming; a cool, wet period from 11.2 to 10.8 cal ka BP; and cool, dry conditions from 10.8 to 10.2 cal ka BP. The record ends with steady warming and increasing moisture. Post-YD climatic variability has been observed at other sites in the northeastern United States and points to continued instability in the North Atlantic during the final phases of deglaciation.

Holocene Record

AbstractA phytolith record from Monte Oscuro, a crater lake located 10 m above sea level on the Pacific coastal plain of Panama, shows that during the Late Pleistocene the lake bed was dry and savanna-like vegetation expanded at the expense of tropical deciduous forest, the modern potential vegetation. A significant reduction of precipitation below current levels was almost certainly required to effect the changes observed. Core sediment characteristics indicate that permanent inundation of the Monte Oscuro basin with water occurred at about 10,500 14C yr B.P. Pollen and phytolith records show that deciduous tropical forest expanded into the lake’s watershed during the early Holocene. Significant burning of the vegetation and increases of weedy plants at ca. 7500 to 7000 14C yr B.P. indicate disturbance, which most likely resulted from early human occupation of the seasonal tropical forest near Monte Oscuro and the development of slash-and-burn methods of cultivation.
