What dune types have horns?

Dune types that have horns are primarily classified as "horned dunes" or "star dunes." These dunes typically exhibit a star-like shape with multiple arms or horns extending outward, formed by the intersection of multiple wind directions. The horns are created by the accumulation of sand at the tips of the arms, influenced by varying wind patterns that deposit sand in distinct areas. Star dunes are often found in regions where wind directions change frequently, such as deserts.
