dc.description.abstract |
The echinoids are described from the middle Eocene Warley Hill Formation, Santee Limestone, and Castle Hayne Limestone of North and South Carolina. Twenty-seven species are present including the following new taxa: <I>Eurhodia baumi, Eurhodia rugosa ideali, Eurhodia rugosa depressa, Eupatagus wilsoni, Eupatagus lawsonae, Linthia harmatuki, Agassizia wilmingtonica</I> Cooke <I>inflata</I>, and <I>Protoscutella mississippiensis</I> (Twitchell) <I>rosehillensis</I>. Three zones are identified: the earliest characterized by <I>Protoscutella mississippiensis</I> (Twitchell) and <I>Santeelampas oviformis</I> (Conrad), a "middle zone" with <I>Linthia harmatuki</I> and the youngest species of <I>Protoscutella</I>, and a "late zone" with large numbers of <I>Periarchus lyelli</I> (Conrad) and <I>Echinolampas appendiculata</I> Emmons. The "early zone" is considered early middle Eocene, the "middle zone" middle Eocene and the "late zone" probably late middle Eocene. The three species of <I>Protoscutella</I> appear to represent an evolutionary series-<I>P. mississippiensis</I> (Twitchell) to <I>P. conradi</I> (Cotteau) to <I>P. plana</I> (Conrad)-characterized by the shifting of the periproct nearer to the peristome.<br/>The echinoids lived in well-aerated sediments in a tropical sea. |
