This was a very varied group of theropods, ranging all from North America and South America to Europe, India and Africa.
Ceratosaurus had very tall lachrymal horns, and had allso a nasal horn, and was about 6 metres, and very robustly built.
A row of low spikes, like in crocodiles has been found across it's spinal chord.

The Noasaurids were some kind of "raptor copies". They were of the same size, and had a
switchable claw, just like the dromaeosaurids. The design of the Noasaurid killer claw,
however, is different from the "raptors". Instead of a know on the lower part of the claw (for muscle attachment) there was a pit.

Abelisaurids had deep compact skulls, and tiny arms. They ranged from 3-8 metres of lenght, and in Carnotaurinae their skulls
were allmost boxy, with tall lachrymal horns, allmost similar to a bull (Carnotaurus means "meat (eating) bull").
In Carnotaurus the arms are extremely small, and has a iguanodontian-kind of thumb-spike.

Carnotaurus is allso about the only big theropod that we god skin-impressions from, showing a robust shelly skin, allmost
like in a crocodile, but not as spiky.
