Conditolepis tenuipunctata (Sannemann, 1955) from the K. crepida Zone at Jabłonna in the Holy Cross Mountains.

Apparatus composition of Conditolepis tenuipunctata.

Diagnoza

P₁ elements elongate and sinuous, with wide smooth platform bearing rounded triangular extension in the middle.

Porównanie

The species may be related to stratigraphically older C. lobicornis, from which it differs in the reduced lobe of the platform. At Wietrznia an early population of this species occurs with P₂ elements virtually lacking the platform, similar to those of C. falcata, that is without a recognizable cusp. Younger samples with P₁ elements typical for the species contain P₂ elements with very wide, oval platform, closely similar to that in more advanced Conditolepis species. A robust appearance of P₁ elements characterizes populations with the platform of P₂ elements already well developed but not reaching the tip of the inner process.
