Palaeomicula jacovidesii Varol & Bowman, 2019
Palaeomicula jacovidesii is a circular nannolith having four smooth imbricated and triangular segments and distinct sinusoidal sutures. The thick imbricated edges of the segments along the sinusoidal sutures can be clearly observed.
Palaeomicula jacovidesii is easily distinguished from the other species of Paleomicula by being circular and having sinusoidal sutures and imbricated triangular segments. Tetralithus quadrisphenus and Palaeomicula maltica have quadrate outlines with wedge-shaped segments.
