Paikasigudem village (Jurassic to of India)

Also known as Chitarampalli; 6 km east of Asafabad Railway Station, Paikasiudem

Where: Andhra Pradesh, India (19.3° N, 79.5° E: paleocoordinates 31.0° S, 32.2° E)

• coordinate stated in text

• outcrop-level geographic resolution

When: Upper Member (Kota Formation), Toarcian to Toarcian (182.7 - 170.3 Ma)

• "On the basis of fishes, the Kota Formation has long been considered to be of Liassic age (King 1881; Robinson 1970). However, several workers noticed the similarity of Kota fishes with the European Toarcian fishes (Schaeffer and Patterson 1984). Patterson and Owen (1991) suggested that the major marine transgression during the Toarcian might have been instrumental for the invasion of the European Liassic fishes in the circumtethyean continents including parts of Indian subcontinent. Recovery of Darwinula, an early Middle Jurassic ostracod, led Govindan (1975) to suggest a Middle Jurassic age for the Kota Formation. Analysing the faunas of the underlying Dharmaram Formation and of the lower and upper units of the Kota Formation and comparing them with faunas from coeval horizons, Bandyopadhyay and Roychowdhury (1996) and Bandyopadhyay and Sengupta (2006) suggested that the Lower Kota Formation has an age ranging from Sinemurian to Pliensbachian, while the age of the upper Kota is Toarcian and may even be extended to Middle Jurassic (?Aalenian)." (Bandyopadhyay et al. 2010)
