“…The findings from the middle Eocene are many: NE Spain (Carrasco, 2021; Gàsser, 2000; Llansana & Romero, 2016), Biarritz in Southwestern France (Castex & Lambert, 1920), Angoumé in Southern Aquitaine-France (Roman & Cahuzac, 1992), Carinthia in Southern Austria (Collignon, 1930), Italian region of Veneto (Oppenheim, 1901), Provence and southern French Alps (Bodelle et al, 1970; Lambert, 1918), Persian Gulf (Roman, 1976), Oman (Roman & Cahuzac, 1992), Egypt (Ali, 2017; De Loriol, 1881; Elattaar, 2018) and from the Bartonnian-Priabonian range of Istria (Mikuž et al, 2014). The material studied herein represents the first record from the middle Eocene of India.…”

This article reports two echinoid taxa viz. Ilarionia sindensis Duncan and Sladen (1884) and Porocidaris schmidelii Münster in Goldfus (1830) from the middle Eocene Sylhet Limestone of Mikir Hills, Assam. P. schmidelii is found from the Lutetian (middle Eocene) to the Priabonian (upper Eocene) in the following regions: NE of Spain, Biarritz (Southwestern France), Angoumé (Southern Aquitaine, France), Carinthia (Southern Austria), Venetian region of Italy Provence, Southern Alps of French, Istria (Croatia), Persian Gulf, Oman and Egypt. I. sindensis was first reported from the Eocene of Sindh province from the Khirthar Series (Pakistan) and Madagascar. It is also recorded from the Bartonian–Priabonian in the following regions: NE Spain, Biarritz in Southwestern France, Angoumé in Southern Aquitaine-France, Carinthia in Southern Austria, Italian region of Veneto, Provence and southern French Alps, Persian Gulf, Oman, Egypt and Istria. They are systematically described to know their stratigraphic, palaeoenvironment and palaeogeographic distribution. The material studied herein represents the first report from the middle Eocene of India, and it significantly expands the geographical extension of Eocene marine echinoids in the northeastern part of India.
