Meet the Carnosaurs?

Feel free to ignore this post; I'm just making some notes for myself.  If I decide to do a "meet the carnosaurs" series of posts, I want to archive exactly who the carnosaurs are.

For my purposes, "Carnosauria" is essentially equivalent fo "Allosauroidea" plus the uncertain possible non-allosauroidean carnosaurs Becklespinax and Gasosaurus.  In addition, there are a few "wild card" taxa that tend to throw cladograms off because they are too poorly known and therefore don't render well.  I'll be treating them alongside these potential basal elements; not because they are believed to be basal necessarily, but because with all three we really don't know for sure where they fit: Poikilopleuron, Xuanhanosaurus, and Streptospondylus.  Erectopus is the final basal member; inside Allosauroidea, but outside any of the other main families.

So, this first group includes:

• Becklespinax
• Gasosaurus
• Erectopus
• Poikilopleuron
• Xuanhanosaurus
• Streptospondylus.

The most primitive and earliest appearing family within Carnosauria is the Metriocanthosaurs, also sometimes known as the Sinraptors.

• Two species of Yangchuanosaurus
• Shidaisaurus
• Metriocanthosaurus
• "Sinraptor"
• Sinraptor
• Siamotyrannus

The Allosaurs are the classic representatives of the group.

• Allosaurus (including African and European members of the genus)
• Saurophaganax
• Epanterias
• Possibly Labrosaurus and Creosaurus

As we get into Carcharosaurodontia we get one specimen, and then the remainder of the Carcharodontidontid tribe

• Datanglong
• Acrocanthosaurus
• Concavenator
• Eocarcharia
• Kelmeyisaurus
• Sauroniops
• Shaochilong
• Veterupristisaurus
• Carcharodontosaurus
• Giganotosaurus
• Mapusaurus
• Tyrannotitan

The Neovenators and Megaraptorans are the final group, which are often controversially placed elsewhere.

• Chilantaisaurus
• Neovenator
• Fukuiraptor
• Siats
• Aerosteon
• Australovenator
• Megaraptor
• Orkoraptor
• Rapator

Although there was some significant controversy about where some specific tyrants fit, the carnosaur family tree is quite a bit more of a mess yet, and I'll probably have to keep those groups fairly fluid.

In Ye Olde Days tyrannosaurs were believed to be carnosaurs, because any large predatory dinosaur was believed to be a carnosaur.  They are now proven to be coelurosaurs.  The other significant groups of large predators that are neither tyrants nor carnosaurs include the megalosauroids, the spinosaurs, and the ceratosaurs, including abelisaurs.  Maybe the dilophosaurs can count too as early "on their way towards being big predators" early therapods.
