A deep-sea agglutinated foraminifer tube constructed with planktonic foraminifer shells of a single species
Abstract. Agglutinated foraminifera are marine protists that show apparently complex
behaviour in constructing their shells, involving selecting suitable
sedimentary grains from their environment, manipulating them in three
dimensions, and cementing them precisely into position. Here we illustrate a
striking and previously undescribed example of complex organisation in
fragments of a tube-like foraminifer (questionably assigned to
Rhabdammina) from 1466 m water depth on the northwest Australian
margin. The tube is constructed from well-cemented siliciclastic grains which
form a matrix into which hundreds of planktonic foraminifer shells are
regularly spaced in apparently helical bands. These shells are of a single
species, Turborotalita clarkei, which has been selected to the
exclusion of all other bioclasts. The majority of shells are set horizontally
in the matrix with the umbilical side upward. This mode of construction, as
is the case with other agglutinated tests, seems to
require either an extraordinarily
selective trial-and-error process at the site of cementation or an active
sensory and decision-making system within the cell.

The Journal of Micropalaeontology (JM) is an established international journal covering all aspects of microfossils and their application to both applied studies and basic research. In particular we welcome submissions relating to microfossils and their application to palaeoceanography, palaeoclimatology, palaeobiology, evolution, taxonomy, environmental change and molecular phylogeny.
