Dr. N.M. Nampothiri (Kizhakke Neelamana in Chengannur, 17 April 1943 – 30 March 2017) was an Indian historian, a former college professor at Malayalam PG Centre- Sree Punnasseri Neelakanta Sharma Memorial Government Sanskrit Collage, Pattambi, Palakkad District, Kerala. He died at Alappuzha at 12.30 hrs on 30 March 2017 after prolonged illness. 
In an interview with Asianet News in 2006, a Malayalam News Channel, he said the artifacts excavated so far from Pattanam does not prove the location is that of Muziris. His perspective on findings in Pattanam is that the excavated pottery sherds assures that they were here, but not assures there existed an ancient harbour. io According to Dr Roberta Tomber, of the British Museum, even if Muziris has been found, one mystery remains - just how it disappeared so completely in the first place. Muziris remains almost a mythical port, an ancient rendezvous for trade between Rome and southern India - but it appeared to have simply disappeared.
