It's unknown why the animal was laying there. It may have something to do with the fact that the main deity of Gebel el-Silsila was Sobek, the god of crocodiles who controlled the waters.
Moreover, Nilsson and Ward discovered another crocodile a little further north laying in a similar position, although this time the tail was pointing north and the head, again missing, lay toward the south.
"We can not verify that these crocs were deliberately placed within the necropolis, or whether they died of natural causes. But to find two in similar circumstances is worthy of further research and analysis," Ward said.

A preliminary study of the vast amount of human remains so far recovered from the necropolis indicates the individuals were generally healthy.
"Very little evidence of malnutrition and infection has been discovered," Nilsson said.
Fractures of the long bones and increased muscle attachments among the skeletal remains indicate behaviors related to a hard labor.
"However, many of the injuries appear to be in an advanced stage of healing, suggesting effective medical care," Nilsson said.
As for the child burials, they clearly reveal that families lived at the quarry site.
"Several child remains show signs of illness, but unfortunately it is too early to state what type of disease or whether this was cause of death," Nilsson said.
