Overview

Excerpt from Figures and Descriptions of Canadian Organic Remains: Decade II, Graptolites of the Quebec Group The specimens which have usually been observed or represented are simple disconnected stipes, doubtless the dismembered or fragmentary portions of fronds, which, presenting in the different species great varieties of form and aspect when entire, are nevertheless composed of parts so similar that these fragments, though indicating specific differences, Offer little clue to a knowledge of the entire form. The name Graptolithas was established by Linnaeus in the first edition of his Systema Naturae, 1736, and applied by him to the straight or curved forms which are serrated (celluliferous) upon one side only, of which G. Sagittarius has been regarded as the types? The propriety of this term is more readily perceived in its application to the fragments of the stipes of monoprionidian forms than to the central portions of the body of the same. In the spirally-enrolled forms, or those with four or more stipes uniting in a central disc, as well as in the variously-branching forms, the analogy is not so perceptible.
