ANGULO, RODOLFO J.; GIANNINI, PAULO C.F.; SOUZA, MARIA CRISTINA DE  e  LESSA, GUILHERME C.. Holocene paleo-sea level changes along the coast of Rio de Janeiro, southern Brazil: Comment on Castro et al. (2014). An. Acad. Bras. Ciênc. [online]. 2016, vol.88, n.4, pp.2105-2111.  Epub 10-Nov-2016. ISSN 0001-3765.

The present work discusses and reinterprets paleo-sea level indicators used to build Holocene sea-level curve for the coast of Rio de Janeiro at former works. We conclude that: (a) the paleo-sea levels inferred by vermetid remains show that sea-level has fallen over the past 4400 years, at least; (b) the paleo-sea level inferred by the beachrock facies and dated shells of Jaconé shows that sea-level was near the present elevation between 8198 and 5786 years before present; and (c) several shells from other beachrocks were deposited probably thousands of years after the specimens died and consequently do not allow precise reconstructions of paleo-sea levels. These conclusions differ from the conclusions of the original paper.
