Deinobrontus

The Deinobrontus was a large, dracian kolonpod that lived in what is now Bardonia. It is the largest known member of its group reaching a whopping 40 meters in length and a massive 78 tons of weight. It is one of the first discovered dinosaurs and was reveled as one of the best fossils until it was eaten by goblins as they had a believed that it was haunted and needed to be eaten to rid it of its curse.

Discovery
Before the siege of Bardonia City a farmer stepped on a bone. At first it was thought to be a tree at the sheer scale of the fossil. It is the first hung, named, and described fossil from Bardonia. At first it was described as a large, wingless dragon, but then a rather nit picky paleontologist, a great quality to have as one, pointed out its foot structure and reclassified it as a Kolonopod. The fossil was so complete that the paleo-art of the creature was accurate enough to be used reasonably. The head miraculously survived the siege but was then stolen by goblin bandits that ate it for religious reasons.

Another discovery at a construction site lead to the discovery of the Sp. holotype, and shortly after this another species, the lentus holotype was found in Ryzan, still inside the Bardonia springs formation as the rocks are the same. About a decade later the grandis holotype was discovered before getting eaten by goblins again. And this year the Supremus joins the species of Deinobrontus, named for its larger, colorful quills.

The only species with significant fossil evidence are the magna and supremus, both preserved some soft tissues like their quills and trunks.

Evolution
The early members of Kolonopods evolved a large nose to show off, but this trait existed in both genders. Muscles randomly mutated into the nose as it kept getting larger. The first truly trunked species was still small, but then the local camarasaurus went extinct and the sauropods rapidly increased in size until they became larger than the camarasaurus. They are the confirmed largest land animal ever, and they have evidence of fighting. A lot. The only adult fossil has 18 spur scars on the bone. They would likely have been nearly invulnerable as an adult, but the smaller individuals would have been under threat by Maip macrothorax and Tsartitan primus.

New Idea of their origins: new evidence supports interference from my species (Sue Bloodfeather Ironclaw of Earth) where they used this small region as testing for seeding planets, this area has recently pulled up evidence of Tripod foot prints that show it was directly tampered with at some point in time

Biology
The Deinobrontus magnas and the Deinobrontus Sp. Body was designed to hold up its massive, 78 ton mass( Sp. specimen was a baby that shows it was going to grow about 20 tons more than this). The body was filled with air sacks to lighten the body and its bones were hollow to keep it lighter, but even with this they were still massive. Their front foot has a giant spike intended to rip and tear at rivals for mates. When ever being attacked they would use their spike to defend themselves, they could also stomp on top of the attackers, or use their thagomizers to stab their attackers. The hood of the creature was extremely light and was able to extend in size in intimidation to seem bigger, but this was likely only used for intimidating other members of the species.

The smaller ones all weighed about the same amount at around 30 tons and likely would have stayed on land most of the time to avoid competition with the much larger species and would avoid competition with each other by eating only a specific species of tree, this was quite easy as this was an extremely diverse ecosystem that could support over 100 different tree species.

Behavior
The behavior of this creature is rather unknown but it likely fed off the taller trees in its unique environment. The trunk was most likely used to grab food and to amplify their noises to communicate with others in its herd. They had large eyes likely used to look out for predators in early life as they likely did not care for their young. They likely would have likely found heated springs, which there is evidence for this there has been prehistoric tuff found in the region. They likely migrated like modern birds and dragons to mating grounds. They lived in a rain forest that had massive, deep rivers filled with an extinct group of aquatic trees that we have evidence that they ate. This shows that they were likely aquatic and would occasionally go underwater to eat the tasty trees. There is evidence that almost every animal in the region was somewhat semi aquatic or completely aquatic. They likely only defended themselves underwater as that was one of the few places that animals large enough to harm them existed. On land these creatures would have been able to use their weapons for a variety of reasons. They likely pushed down trees that were in their path of were too tall for their trunk to reach the tops of them. They had a very flexible neck that would let them both graze on lower vegetation and on higher vegetation quite clearly.
