Archaeologists Baffled By A 2,000-Year-Old Skeleton Found In Scotland With Its Brain Scooped Out And Its Bones Turned Into Tools
The Iron Age is different, at least in Britain and particularly in Scotland.
The construction of large communal tombs declined dramatically.
Formal, marked burial sites become archaeologically rare.
This does not mean that Iron Age people stopped having dead people — population size and normal mortality rates guarantee that Iron Age communities produced their dead at roughly the same rate as any other period.
What it means is that they were treating their dead in ways that left fewer or more ambiguous traces in the physical record.
The most plausible explanations for the relative invisibility of Iron Age British dead involve practices that would not have left clear archaeological traces.
