The Brachiosaur Parade

©2009 Paleo-King

Featured on The Paleo King [link] and SV-POW [link] - it's the Big Bad Brachiosaur Parade!

The fourteen best-known brachiosaur genera as of mid-2009 (before Abydosaurus and Qiaowanlong were described - sheesh, I wish they'd been discovered and described a few months earlier!). All brachiosaurs drawn to scale with the largest known T. rex specimen (MOR 008, not Sue) and labeled for easy reference 8-)

Here's the lineup:


"the Archbishop"

The footprints at the bottom are those of Pleurocoelus and Breviparopus.


Note: The "Brachiosaurus" shown here was B. brancai, which is now formally known as Giraffatitan (though the alternate name has been used since 1988, first and foremost by Gregory Paul). However, the type species B. altithorax was of similar average size.

The entire sequence is roughly in order from the earliest brachiosaurs to the last, with the exception of the basal dwarf brachiosaur Europasaurus.

Beautiful! Wish we had more conclusive proof of the existence of Breviparopus, though

Any plans on updating this someday? By the way, this is the best dinosaur size comparison there is, in my opinion. 
Paleo-King's avatar
I may update it, but overall not much would change apart from the sizes of a few of these species, and a few proportion changes with Lapparentosaurus and the other basal ones. I'm surprised how well this thing has aged.

Are you did compare size to Spinosaurus version.
Paleo-King's avatar
Spinosaurus would be about half a head longer than the T. rex.

I put T. rex in there because that's just about everyone's favorite "standard" demarcation line for determining which dinosaurs are true giants and which are merely large.

archbishop is actually a very fitting name for a sauropod i think of the long chess piece :D
Paleo-King's avatar
LOL the chess piece with the huge hat... imagine if they find its skull and the crest turns out to be twice as tall as Giraffatitan's. :XD:
Evodolka's avatar
that would be interesting, though i thought you were going to say
"imagine if it had a crest like a bishop hat"
THAT would be more interesting :XD:
Paleo-King's avatar
That's a very weird crest indeed... A bishop hat would require a deep notch in the nasal bone itself... like a v-curve in a heart monitor. LOL that would be the day ... :P

Though we might see a brachiosaur with a crest of comparable height to a bishop hat. That's if you're talking about those super-tall catholic bishop mitres. If it's the eastern orthodox church, there's already a whole family of dinosaurs that resemble their bishops' hats. Pachycephalosaurs.

"BREAKING NEWS paleontologists find a bishop hat on top of a sauropod skull"
i really do hope that happens now :XD:

wait it's already a thing?
i was thinking the chess piece
i actually know very little pachycephalosaurs
Paleo-King's avatar
Well pachycephalosaurs have a dome, like the shape of eastern orthodox bishop hats (russian church, greek church, etc.). they wear a domed crown not a miter. Mycocephale REALLY looks like those hats.

Miters (tall pointy hats with the notch) like you see on the chess piece are mainly catholic bishops and a few other western churches. No dinosaur has a head that shape... that we know of.

oh i think i know who you mean now, yeah i can see it :D

thanks for the info
now you got me thinking of chess and how i really want to make dinosaur chess pieces :XD:

What about Giraffatitan?  That guy was enormous, too.
Paleo-King's avatar
The "brachiosaurus" in this image is actually Giraffatitan. This was made before the name Giraffatitan became official. Speaking of which.... check this out:…

I know this is quite old, but is it relatively certain that the footprints are those of Pleurocoelus and not of some larger species from the same time and place? Most estimates online seem to put it at 60 feet long or less, though I don't know what they're based after.

What about Amphicoelias fragillimus?  Isn't that the biggest one?
Paleo-King's avatar
That's a diplodocoid, not a brachiosaur. This is the brachiosaur parade. If this were a diplodocoid parade then perhaps I would include Amphicoelias fragillimus. Or maybe not, as it's only known from a single bone which was either lost or destroyed more than a hundred years ago.

Inc wich country did they find these footprins they named Breviparopus ?   Nice chart btw.
mikebrownsound's avatar
Sweet.  That would be enormous.  Bigger than Argentinosaurus i can imagine.
bricksmashtv's avatar
Well, taller and longer, but not heavier. Brachiosaurs were way lighter than Titanosaurs of similar size, but still heavier than Diplodocoids of the same size [85 feet long: 45 Tons (Titanosaur)>35 Tons (Brachiosaurs)>15 Tons (Diplodocoid)].
