“…Similar differences between live and dead assemblages due to the dissolution of calcareous species have been noted in other studies (e.g. von Daniels, 1970;Goldstein and Harben, 1993;Goldstein et al, 1995;Collins, 1996;Watkins, 1998, 1999;Edwards and Horton, 2000;Horton et al, 2005;Culver and Horton, 2005). With respect to sea-level studies, Edwards and Horton (2000) noted during a study of Arne Peninsula, South England, that reconstruction techniques performed reliably in the high marsh zone where agglutinated foraminiferal species are dominant.…”

“…However, in lower marsh environments where calcareous species are prevalent, post-mortem test dissolution alters the fossil assemblages and leaves them without modern analogues. Thus, to circumvent this problem, Edwards and Horton (2000) had to develop new reconstruction techniques based on agglutinated foraminifera and utilising preserved test linings.…”

In terms of foraminiferal distributions within the intertidal zone, there is a clear distinction between an agglutinated assemblage that is restricted to the vegetated marsh and a calcareous assemblage that dominates the mudflats and sandflats of the intertidal zone.…”

We have collected live and dead foraminiferal times-series data at 2-weekly intervals for a 12-month period from the intertidal zone of Cowpen Marsh, Tees Estuary, UK. The data from the 689 samples show profound differences between live and dead assemblages, although assemblages are dominated by just three species, Haynesina germanica, Jadammina macrescens and Trochammina inflata, which represent over 70% of the assemblage. The cumulative increase in species of most environments approximates to a lognormal or log series. None of the datasets show a broken stick pattern. The cumulative maximum number of species, which represents the species carrying capacity of the environment, is recorded earlier in the life assemblages than the dead counterparts. The dead assemblage of Cowpen Marsh is found to have a higher abundance (435 compared to 163 individuals/10 cm 3 ) and number of species (52 compared to 28) than its live counterpart because the dead assemblage represents many generations added over a long period of time. In contrast, some species are recorded in the live dataset that were not found in the dead assemblage, indicating the dead record is either incomplete (e.g. taphonomic change) or inadequately sampled.We investigated the influence of patterns in cumulative increase on dead assemblages for sea-level reconstructions through the development of foraminiferal-based transfer functions. The cumulative transfer functions suggest that the performance improves during the first six sample intervals of the time-series dataset with reconstruction differing by 1.2 m and remains constant thereafter.

“…Without this performance test, it is possible that the transfer function will output a reconstruction for which there is no modem analogue, resulting in an index point that could potentially be erroneous. MAT can be used to highlight instances where there is no good modem analogue due to uneven spatial sampling or as is the case with Edwards and Horton (2000), where the dissolution of calcareous tests in the fossil record causes fossil tidal flat areas to be different to contemporary tidal flat areas. Edwards and Horton (2000), present a training set compiled from 10 contemporary sites around the UK.…”
