Abstract

Abstract The study of Silurian sediments in the central part of the Altai Mountains (Gorny Altai) by limestone dissolution has revealed two groups of spherical objects; large microspheres 90–120 µm and small nanofossils (nanospheres) 5–18 µm in diameter. Their double-layered walls are composed of standard-sized siderite microcrystals replaced by goethite. The Altai microspheres have a low Ca content (<0.5 wt %) so cannot be interpreted as calcispheres. The Altai Silurian microspheres and nanofossils (nanospheres) are tentatively attributed to biomineralized remains of loricae (shell-like envelopes) of various euglenoid alga generations.
