A literature review of horn and horn-like structures in vertebrates to correlate placement to function, behavior, and niche.

In this paper, the true horns of bovids are compared to the many horn-like structures found throughout the animal kingdom. Literary sources were reviewed for a variety of horn-like structures. The review was limited to extinct and extant terrestrial vertebrates. 3D models of these organisms’ skulls and “horns” were created or acquired and 3D printed at the same scale to illustrate their differences and similarities and to analysis of their comparative size easier between large and small genera.

Comparisons of Schansitherium tafeli with Samotherium boissieri (Giraffidae, Mammalia) from the Late Miocene of Gansu Province, China

We are describing and figuring for the first time skulls of Schansitherium tafeli, which are abundant in the Gansu area of China from the Late Miocene. They were animals about the size of Samotherium with shorter necks that had two pairs of ossicones that merge at the base, which is unlike Samotherium. The anterior ossicones consist of anterior lineations, which may represent growth lines. They were likely mixed feeders similar to Samotherium. Schansitherium is tentatively placed in a very close

Evolution of ruminant headgear: a review

The horns, ossicones and antlers of ruminants are familiar and diverse examples of cranial appendages. We collectively term ruminant cranial appendages ‘headgear’; this includes four extant forms: antlers (in cervids), horns (in bovids), pronghorns (in pronghorn antelope) and ossicones (in giraffids). Headgear evolution remains an open and intriguing question because phylogenies (molecular and morphological), adult headgear structure and headgear development (where data are available) all suggest different pictures of ruminant evolution. We discuss what is known about the evolution of
