Material examined

ESTONIA • 1 spec.; Kärdla quarry ; Kõrgessaare Formation , Vormsi Regional Stage; TUG 1745-201 .

Description

The specimen is a fragment of a very slightly endogastrically curved mature body chamber with conch height, and width at its base of 61 mm and 49 mm, respectively (CHI = 1.44). The preserved part of the body chamber is 65 mm long and tubular in lateral view. The conch cross section is oval with a narrower prosiphuncular side. The siphuncle is close to the conch margin and ca 7 mm wide (RSH = 0.11).

Remarks

In its dimensions, this specimen is most similar to the Norwegian species of Kiaeroceras but differs in having a more compressed conch ( K. frognoyense has a CHI of 1.15, and K. heroyense a CHI of 1.25).
