Genus Carolia Cantraine, 1838

Remarks

The genus Carolia Cantraine, 1838 , is thought to have appeared for the first time in lower Eocene strata of Egypt, India, and Pakistan and to have spread across the Tethyan region during the middle Eocene ( El-Shazly et al. 2016). Specimens from Maastrichtian beds in Egypt identified as examples of Carolia ( Quaas 1902) were subsequently assigned to a new genus, Tarturia Strougo, 1983 ( Strougo 1983) , thought to be ancestral to Carolia (El Shazly et al. 2016) . Species of Carolia have been described from lower and lower middle Eocene beds of India ( Cox 1938) and Oligocene beds in Argentina ( Ihering 1907).
