“…A few 23 moa from PV had been radiocarbon dated and they suggested a late Holocene fossil accumulation: 24 conventional radiocarbon ages spanned the period from 3740 BP to 1245 BP (Kulp et al, 1952; Blau 25 et al, 1953;Gregg, 1972;Burrows et al, 1981). This rudimentary chronology was supported by four 26 radiocarbon ages of sediment layers surrounding the moa remains (Gregg, 1972).…”

the other three moa taxa combined at BHV. A subsample of 227 individuals had sufficient nuclear 28 DNA preservation to warrant the use of molecular sexing techniques, and the analyses uncovered a 29 remarkable excess of females in both deposits with an overall male to female ratio of 1 : 5.1. Among 30 juveniles of E. curtus, the only species which was represented by a substantial fraction of juveniles, 31 the sex ratio was not skewed (10 ♂, 10 ♀), suggesting that the observed imbalance arose as a result of 32 differential mortality during maturation. Surprisingly, sex ratios proved significantly different 33 between sites with a 1 : 2.2 ratio at BHV (n = 90) and an entire 1 : 14.2 at PV (n = 137). Given the 34 mobility of large ratites, and the proximity of the two fossil assemblages in space and time, these 35 differences in taxonomic and gender composition indicate that moa biology and the local environment 36 have affected the fossil representation dramatically and several possible explanations are offered. 37Apart from adding to our understanding of moa biology, these discoveries reinforce the need for 38 caution when basing interpretation of the fossil record on material from a single site. 39 40

The contribution of glacial isostatic adjustment to projections of sea‐level change along the Atlantic and Gulf coasts of North America

We determine the contribution of glacial isostatic adjustment (GIA) to future relative sea-level change for the North American coastline between Newfoundland and Texas. We infer GIA model parameters using recently compiled and quality-assessed databases of past sea-level changes, including new databases for the United States Gulf Coast and Atlantic Canada. At 13 cities along this coastline, we estimate the GIA contribution to range from a few centimeters (e.g., 3 [−1 to 9] cm Miami) to a few decimeters (e.g., 18 [12][13][14][15][16][17][18][19][20][21][22] cm, Halifax) for the period 2085-2100 relative to 2006-2015 (1− ranges given). We provide estimates of uncertainty in the GIA component using two different methods; the more conservative approach produces total ranges (1− confidence) that vary from 3 to 16 cm for the cities considered. Contributions from ocean steric and dynamic changes as well as those from changes in land ice are also estimated to provide context for the GIA projections. When summing the contributions from all three processes at the 13 cities considered along this coastline, using median or best-estimate values, the GIA signal comprises 5-38% of the total depending on the adopted climate forcing and location. The contributions from ocean dynamic/steric changes and ice mass loss are similar in amplitude but with spatial variation that approximately cancels, resulting in GIA dominating the net spatial variability north of 35 ∘ N.

“…Radio-carbon dates place the Upper Capsian sometime between 6848 and 4848 B.C., and the "Neolithic of Capsian tradition" in Tunesia to sometime between 3198 and 2898 B.C. (Kulp et al, 1952), considerably later than comparable Near Eastern material. Africa south of the Sahara probably received its domestic cattle, sheep, and goats from the Nile Valley or Arabia as no wild or fossil relatives of these animals have been found in the area with the exception of Capra tzzlbiana Cuv.…”
