Brachiosaurus

I think he just means that Brachiosaurus is the clade in the analysis with which they share the most characters.

MIWG. 7306 possesses loads of anatomical features that are also present in Brachiosaurus and Sauroposeidon, and it even shares some features that are present in Sauroposeidon and not in Brachiosaurus but, so far as we can tell, it doesn’t possess any features that are unique and thereby allow it to be reliably differentiated from all other sauropods.

Regardless, Greg Paul erected the subgenus Giraffatitan, and placed the African species, B. brancai in it, so that the species became properly known by the rather unwieldy name Brachiosaurus (Giraffatitan) brancai.

Instead of referring to Brachiosaurus (the long-necked plant-eater that makes an early appearance on tonight's show) or Carnotaurus (the toothy, horned dinosaur that almost runs down Terra Nova's patriarch in the episode), use more generic names (brachiosaurs or abelisaurs, respectively).

So even though the long-necked, plant-eating dinosaur known as Brachiosaurus died out long before Tyrannosaurus rex came onto the scene, their cousins can mix it up in the computer-generated landscape created for "Terra Nova."

"Finally, I beg forgiveness from all brachiosaur lovers, that so beautiful an animal as 'Brachiosaurus' brancai now has to be known by so inelegant a name as Giraffatitan."

Scientists say Fruitadens haagarorum lived about 150 million years ago, during the Late Jurassic period, probably darting between the legs of much larger dinosaurs such as Brachiosaurus, Allosaurus and Torvosaurus.

We know that brachiosaurids such as Brachiosaurus possessed a short, small thumb claw, but Lower Cretaceous trackways apparently produced by other brachiosaurids indicate that the thumb claw was absent in these forms (it’s been suggested that the thumb claw was still present in these forms, but that it was so small that it failed to leave an impression.

Presumably, ‘C.’ humerocristatus was built much like better-known brachiosaurids (such as Brachiosaurus: adjacent image is Greg Paul’s old restoration of Brachiosaurus with Ceratosaurus and pterosaurs), but it was surely different in various of its details.
