[3] Amutria is mentioned in Ptolemy's Geographia (c. 150 AD) in the form Amutrion (Ancient Greek: Ἀμούτριον) as an important Dacian town, at latitude 50° 00' N and longitude 44° 45' E (note that he used a different meridian and some of his calculations were off[4]).

[3] Amutria is also depicted in the Tabula Peutingeriana (2nd century AD) between Drubetis and Pelendava, on one of the three roads build by Emperor Trajan in Dacia.

[7] Amutria is hypothetically located at one of the following sites in Oltenia (Southwestern Romania): Based on the archaeological survey and excavations performed at Cătunele in 1885,[8] 1973, and later in 1981-84, a Roman castrum and civilian settlement was discovered.

It is bordered in the east by the Chivădarul River and was intended to oversee the Valea Motrului mountainous region inhabited by a large Dacian population.

The road was connecting this site to Castrum Pinoasa, passing through the modern villages of Glogova and Apa Neagră then heading towards Tismana River.

[9] Locating Amutria at Botoșești, a site with a very rich evidence of a Roman presence, has a problem: it is not by the Motru river and does not fit the Ad Mutrium toponym connection.

[12] However, there are two significant archeological sites cataloged by the Romanian National Institute of Historical Monuments: Cetatea Micului (LMI code DJ-I-s-B-07875), a Dacian fortress from late La Tène Period (1st century AD) and Piscul cazacilor (LMI code DJ-I-s-B-07876) site which includes a Dacian fortress (La Tène Period) and a Daco-Roman settlement (2nd - 4th century).

[13] Piscul Cazacilor is one huge area (over two kilometres long) with lots with Roman artefacts, including pottery, bricks, and dressed stones.
