You'd be amazed at how many dinosaurs are known from very few bones. I think they have enough here and hell, they know what they're talking about. They do also acknowledge that the bones come from two individuals of different sizes. Yes there are dinosaurs known from very few bones and some from just a single tooth. But how can you really tell if they know what they are talking about. It's just speculation. How did I know that if I said something you would say I was wrong?

A lot of the reconstruction IS just speculation. They make that clear. However they can tell that it's a camarasaurid with robust hips, and that the fossils are from two individuals. Edit: were you referring to the criticisms made by Jim Kirkland? Matt Wedel has posted a response: svpow.wordpress.com/2011/02/25/clearing-the-air-about-brontomerus/

Read about this on the BBC website. I wonder how long it will be until it comes out as a toy? Would be a nice variant on the generic sauropod image.

The only problem with toys like that being released is that it will probably be indistinguishable from most every other sauropod figure out there. Whatever distinguishing features this creature had most likely wont be carried over into a toy form, unless it was something really wild like spikes or armor.

My thoughts were completely arrived at independently and haven't changed. Will see what comes of this.

Let's not forget that they are proposing a kicking action for a dinosaur, whose legs and most all of it, haven't yet been discovered. This reminds me of Vulcanodon which was named for some jagged edged teeth, which most likely belonged to some carnivore, that were found in the area. Some were calling it the missing link between pro-sauropods and sauropods. Now it's not believed to be connected. I wonder what dinosaur name we should use for the jagged edged teeth? ;D

They're saying it had very large leg muscles, which based on the size of the pelvis and the huge areas for muscle attachment it clearly did. The kicking thing is specualtive of course...but then most dinosaur behaviours are!

How nice a mother with its baby kicking a Utahraptor. Problem is evidence doesn't support parental care in sauropods. And Utahraptor was no where around when Brontomerus walked the earth.

"A recently discovered dinosaur used to kick its predators with great wrath and a bad temper" "Brontomerus mcintoshi, 14 meters long, had an inmense razor in its hip bones, where strong muscles attached" "It would have possibly attacked chicken-sized animals by kicking and stamping them until death" Translated from mx.ibtimes.com/articles/10458/20110228/dinosaurio-patadas-depredadores.htm ;D ;D

Very likely, not!!!

Something lost in translation maybe? Taylor et al never mentioned chickens! ;D

If an animal has legs, it can kick.
Also, the whole "sauropods didn't care for their young" bit.. Not saying it's wrong, but how much info do we have on the lives of sauropod young and for what percentage of known species?

Not saying it's wrong, but how much info do we have on the lives of sauropod young and for what percentage of known species? Brontomerus is most closely related to Camarasaurus. Their eggs have been found like many other sauropods laid in a linear pattern and not in a nest. This leads us to believe they laid their eggs while they were walking and simple kept going. See Walking With Dinosaurs. Also sauropod walkways show herds segregated by age with juveniles forming groups seperate from adults. Another problem is sauropod hatchlings were only about a foot long and would have been easily trampled by adults. Titanosaurs on the other hand do appear to lay eggs in a nest, and may have given some care to their young.

One more mistake to add to the list.

Any theories on what baby sauropods did for protection after they were hatched? Modern critters that grow up without mommy are able to outrun predators in some cases, or they are small enough to hide from most everything, OR they are just so numerous that even when you kill 90% of them, the 10% that is left is enough to keep the population going.

Apparently, Wikipedia has picked up on the "kicking theory" too. As for the behavior of the young, I'd compare them to baby sea turtles. With no affective way to escape predators (at least while very young) they would rely on their massive numbers to ensure that some survive.

I don't think dinosaurs could move their legs sideways!
