Although T. sethi was named after the god Seth for having a crest similar to his crown, Seth did not wear such a crown; the crest was instead similar to the crown of Amon (left).

The crest of T. sethi has been compared to a toucan's bill.
It was originally suggested that T. sethi (right) fed like an extant skimmer (left), but this theory has been criticised.
