The fragmentary nature of the remains, the mixing that occurred during the initial disturbance by the construction equipment, and the long period between the discovery and the most rigorous modern analyses have all contributed to uncertainty about whether the burial represents one individual or more.

Some researchers accept that the burial contained only the young child; others maintain that the two-individual interpretation is possible.

The specific relationship between the artifacts and the human remains — which artifacts were definitely in direct association with the remains, and which might have been in adjacent but separate contexts — is also uncertain, given the circumstances of discovery.

The overall pattern of association is clear, but the precise spatial relationships that would allow the most detailed interpretation of the burial’s structure are not fully recoverable.

The sex of the Anzick child is another question that has not been definitively answered from the skeletal material alone.
