carcases

Bianucci et al suggested that Perucetus might have browsed on coastal fish and shellfish, or scavenged carcases, as some sharks do.

Toxicology analyses, including immediate testing for cyanide, which is sometimes used to kill elephant in Zimbabwe, as well as more sophisticated analyses done in UK, found no traces of poisons in the carcases or at a waterhole close to many of the carcasses.

Mammals that scavenge dead bird carcases, including foxes, otters and seals, have also been infected.

The Scottish government said the disease was also affecting wild bird populations elsewhere in the world, and it had published updated advice on the reporting, collection and safe disposal of wild bird carcases.

The carcases were pulled ashore and distributed to locals for consumption.
