exhibits markedly different successional patterns of spacing of microlaminae; first, a closely spaced phase that includes a very limited development of pachystele structural elements, only some very short, rather scattered, micropillars; and secondly, a wide-spaced phase that includes a full range of longitudinally orientated features, such as upward-flaring pachysteles with acosmoreticular microstructure, and wavy, microlamina-like dissepiments. Examples of the close-spaced phase with sets of up to four microlaminae occur at irregular intervals through the skeleton. In contrast,
