lingulate

The section was sampled during fieldwork in 1987 as follows: pebbles from the basal conglomerate of the Ulgase Formation (N-62), lingulate brachiopod shells from the Ulgase Formation (N-63 and N-63A), and basal lingulate shell coquina of the Kallavere Formation (N-60).

Stem erect, usually unbranched or with very few short branches (0.5-1.5 cm); stem transverse section round-oval, with central strand, large and thin-walled medullar cells and 1-2 rows of yellowish thick-walled cells, without hyalodermis; axillary hairs scarce (1-2 per leaf axil), with 1-2 hyaline apical cells; pseudoparaphyllia foliose, broadly triangular, lingulate or irregular.

The Ulgase Formation has yielded lingulate brachiopods Ungula inornata from all levels above the basal coquina, Ceratreta tanneri from the upper 3 m and Ungula sp.

Most readily recognized by the shape and patterning of the male supra-anal plate with a wide lingulate terminal process (Fig.

The end-phase lattice parameter a value is similar to the heated lingulate shell apatite (Nemliher et al.

The above studies suggest that fossil lingulate shells may contain a wide range of apatite varieties precipitated in different conditions.

Early Ordovician lingulate brachiopods from the Emanuel Formation, Canning Basin, Western Australia.

According to Williams & Cusack (1999), lingulate brachiopods have baculated shells.

Leaves spreading, 7585 cm long, moderately coriaceous, green adaxially, tinged red abaxially; leaf sheaths elliptic, 10 x 6 cm, entire, nerved, castaneous toward the base, punctate-lepidote, more so adaxially; leaf blades lingulate, acute and mucronate, 3550 mm wide, punctate-lepidote, subdensely serrate with dark, mostly antrose 13 mm long spines.

The drill core data show that the maximum diversity of fossils, such as rhynchonelliformean and lingulate brachiopods, gastropods, tentaculitids, and calcareous algae, is in the lower half of the Kuldiga Fm., which is also characterized by high carbon isotope ([[delta].sup.13]C) values.

Leaf sheaths elliptic, 6-8 x 3u5 cm, somewhat castaneous toward the base, subdensely brown punctate-lepidote especially adaxially; leaf blades lingulate, rounded to broadly acute, apiculate, 18u28 mm wide, pale punctate-lepidote, bright green with a few obscure darker green bands or mottled areas.

euryelytra, but can be distinguished by its lingulate leaf blades (vs.
