Title: Use of Radial Pores in Taxonomy and Paleoecology of Ostracoda: ABSTRACT

Author(s): Harbans S. Puri, Bruce E. Dickau

Article Type: Meeting abstract

Abstract:

On the lateral surface of the carapace, ostracodes have radial pores of two types--"simple" and sieve. The functions of these two pore types are not fully known. Studies of the carapace with a scanning electron microscope reveals differences between the pores of Myodocopa, Platycopina, Cladocopa, and Podocopina. Sieve pores demonstrate the greatest dimorphism and are confined to the superfamily Cytheracea. A basic pattern of pores was formulated.

Type A:
Single pore with a sensory hair. A^prime Normal pore without a lip. A^Prime Normal pore with a lip.

Type B:
A sieve plate without a well-defined central or subcentral pore with a sensory hair.

Type C:
Type A superimposed on Type B. A sieve plate with a pore and sensory hair emerging from its center.

Type D:
Combination of Type A and Type B. A sieve plate, and a separate single pore with a sensory hair.

These types can be utilized in future systematic studies of Ostracoda.
