Nature, 1893 I AM glad to find that Mr. Pearcey agrees with me in regarding Neusina Agassizi, Goes, as identical with Stannophyllum zonarium, Haeckel. But with respect to its systematic position I do not as yet see sufficient reason to differ from Prof. Haeckel in regarding it as a sponge, although I have never observed flagellated chambers and cells any more than ...

Foraminifers associated with macroalgae on a wave-cut platform off Abu Qir coastal area, Egypt
Egyptian Journal of Aquatic Research, 2022 Since their earliest history, benthic foraminifers have diversified to inhabit a vast array of habitats, from semi-terrestrial to the deep-sea floor. Epiphytic foraminifers developed morphologies that have allowed them to inhabit macroalgal fronds and ...

Phenotypic Evolution in a Cretaceous Foraminifer [PDF]
Evolution, 1982 Statistically well-documented sequences of fossil species are rare, as has been observed, for example, by Eldredge and Gould (1972), Boucot (1978) and Dodson and Hallam (1977). Rapid advances in theoretical paleontology made over the last few years have, however, made it imperative that the many new and exciting theories we now have at our disposal be ...

Birth, life and death of the Pannonian Lake [PDF]
, 1990 The Miocene-Pliocene Pannonian Lake formed in an extensional basin system behind the compressional arc of the Carpathians. Its size and depth were comparable to those of the Caspian Sea.

New robertinid foraminifers from the Early Jurassic of Adnet, Austria and their evolutionary importance [PDF]
Acta Palaeontologica Polonica, 2016 New benthic multichambered foraminifers have been discovered in the Hettangian–Sinemurian of the Northern Calcareous Alps (Adnet, Salzburg, Austria). Originally aragonitic, these forms are completely recrystallized but the early impregnation of their ...

A deep-sea agglutinated foraminifer tube constructed with planktonic foraminifer shells of a single species [PDF]
Journal of Micropalaeontology, 2018 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.
