A study is made of allometric growth in four dimensions of the ammonite Barremites subdifficilis (Karakasch) from the Neocomian of the Crimea. The four dimensions are further analysed simultaneously by the multivariate statistical method of principal component analysis. The results are compared with those found for two species of Triassic ammonites.
