Abstract

Growth of the glabella of the trilobite Dalmanitina olini is studied by plotting various dimensions y against the length of the glabellar stalk x which is taken to represent absolute size. The relations are fitted best by linear equations y = a(x + b/a), and for several dimensions the value of b/a appears to be constant. The concepts of absolute and specific growth-rates are discussed in relation to the glabella of D. olini.
