The term "megalith" (mega: massive; lith: stone) is used to describe these monuments due to the use of large stone blocks in construction. Archaeological literature around the world use this term to refer to a variety of monuments. The studies point to the indigenous development of the ancient Kerala society and its culture beginning from the Paleolithic age, and its continuity through Mesolithic, Neolithic and Megalithic ages.However, foreign cultural contacts have assisted this cultural formation. Archaeological studies have identified many Mesolithic, Neolithic and Megalithic sites in Kerala.These findings can be classified as Menhirs (Pulachikallu), Hood stones (Kudakkallu), Stone circle, Sarcophagus (Savakallara), Hat stones (Toppikallu), Snake hood stones(Pathikkallu), Urn burials(Nannangadi),Cairn (Vazhiyadayaalam).
Menhirs (Nadukkallu)
Nadukkallu or menhir is a stone age monument which was later known in the names pulachikkallu, masathikkallu or veerakallu. These are single rock slabs installed atop a burial site. The nadukallu is mentioned in ancient texts ‘Purananooru,’ ‘Akananooru,’ ‘Malaipadukadam’ and ‘Tolkappiam.’The largest menhir in Kerala was recorded on the Pothamala hills in Udumbanchola taluk. Menhirsare monolithic slab usually made of granite. But themenhir in Anakkara in Palakkad district of Kerala is made of laterite.

Sarcophagus (Savakallara)
A sarcophagus is a legged coffin made of terracotta. Kudakkal, pathikkal, and rock-cut caves are made of laterite. Laterite bricks are still commonly used as building material in the region and this has resulted in the destruction of megalithic monuments.
Topikkal
A topikkal is known as hat stone which is a hemispherical laterite stone used as a lid of a burial urn.

Different types of iron implements have been found placed as burial goods within the megaliths.
These include daggers, swords, axes, nails, sickles and agricultural implements. Another important category associated with megalithic monuments is beads. While they could have been part of ornaments, they are usually found loose, possibly because they were strung together using perishable materials.
