Reptile remains found dumped on the side of an Adelaide roadside have been confirmed as belonging to a saltwater crocodile.

Staff from SA's Department for Environment and Water collected the remains, which were subsequently analysed.

It is still unclear how the remains came to be at the roadside and anyone with information has been urged to contact CrimeStoppers.

Reptile remains found dumped on the side of a road in suburban Adelaide have been confirmed to be from a saltwater crocodile, but how they came to be there remains a mystery.

In a statement, a Department for Environment and Water spokesperson said staff collected the remains which were found among other litter at Coleman Road, Waterloo Corner, in Adelaide's north west in April.

The spokesperson said an analysis had been carried out and the remains were "determined to be those of a saltwater crocodile".

"It is not known how the remains came to be at the Waterloo Corner site," the spokesperson said.

The department has urged anyone with information about the unexpected discovery to contact CrimeStoppers on 1800 333 000 or by visiting the Call it Out wildlife crime portal on the CrimeStoppers website.

"There are no further updates at this stage," the spokesperson said.

Both SA Police and the RSPCA said the matter was under investigation by the department.

"It's obviously come from up north somewhere and it's just odd that it was cut up in such a strange way, straight away," he said.

"It's not someone trying to get the skin or something like that.

"It's probably somebody that shot one (a crocodile) or caught one — quite a bit illegally — and put it in a chiller, or ice or something, and took it down and then decided they didn't know what to do with it."

Professor Webb said the NT's saltwater crocodile population was "strong and robust", but the killing was still against the law.

"They've probably taken it in the territory, illegal
