Corded Ware culture followed by Bell beaker culture
Graves
Burial occurred in flat graves or below small tumuli in a flexed position; on the continent males lay on their right side, females on the left, with the faces of both oriented to the south. However, in Sweden and also parts of northern Poland the graves were oriented north-south, men lay on their left side and women on the right side - both facing east. Originally, there was probably a wooden construction, since the graves are often positioned in a line. This is in contrast with practices in Denmark where the dead were buried below small mounds with a vertical stratigraphy: the oldest below the ground, the second above this grave, and occasionally even a third burial above those. Other types of burials are the niche-graves of Poland. Grave goods for men typically included a stone battle axe. Pottery in the shape of beakers and other types are the most common burial gifts, generally speaking. These were often decorated with cord, sometimes with incisions and other types of impressions. Other grave goods also included wagons and sacrificed animals.
The approximately contemporary Beaker culture had similar burial traditions, and together they covered most of Western and Central Europe. The Beaker culture originated around 2800 BC in the Iberian Peninsula and subsequently extended into Central Europe, where it partly coexisted with the Corded Ware region.
In April 2011, it was reported that an untypical Corded Ware burial had been discovered in a suburb of Prague. The remains, believed to be male, were orientated in the same way as women's burials and were not accompanied by any gender-specific grave goods. Based on this, and the importance usually attached to funeral rites by people from this period, the archaeologists suggested that this was unlikely to be accidental, and conclude that it was likely that this individual "was a man with a different sexual orientation, homosexual or transsexual", while media reports heralded the discovery of the world's first "gay caveman". Archaeologists and biological anthropologists criticised media coverage as sensationalist. "If this burial represents a transgendered  [sic] individual (as well it could), that doesn't necessarily mean the person had a 'different sexual orientation' and certainly doesn't mean that he would have considered himself (or that his culture would have considered him) 'homosexual,'" anthropologist Kristina Killgrove commented. Other items of criticism were that someone buried in the Copper Age was not a "caveman" and that identifying the sex of skeletal remains is difficult and inexact. Turek notes that there are several examples of Corded Ware graves containing older biological males with typically female grave goods and body orientation. He suggests that "aged men may have decided to 'retire' as women for symbolic and practical reasons." A detailed account of the burial has not yet appeared in 
scientific literature.
