There is more predators than that Bradycneme Pyroraptor Elopteryx Pannoniasaurus Eurazhdarcho among others |

Balaur may not have even been a predator; it seemed to be more of a generalistic omnivore with herbivorous tendencies. Plus, since it was likely an avialan rather than a dromaeosaurid, the assumption that it was definitely a predator is already flawed. |

AFAIK Balaur alleged herbivory was recently shot down, it just was overly more robust than most dromeosaurids it's size. |

Any sources on that? I'd be interested in reading. I've never been 100% sold on it, I always figured generalistic omnivory was more probably. |

I keep asking about biomes for some weird reason.... would temperate rainforest be a good biome for lambeosaurus m? is it possible to replicate any dinosaurs sounds other than parasauraloaphus (such as corithosaurus) |

The hypothesis was thought up by Andrea Cau on his blog in response to some of the aberrant features that made Balaur what it was. An alternative to the bulky mass murderer that was flooding the media. Cau shot the idea down himself on his blog again a few months later. Further research on his part suggested that the known Balaur remains showed some consistency with Fowler's proposed hunting strategy which paid close attention to dromaeosaur foot anatomy.

Would you look at me? I'm setting records.

Yeh. Lambeosaurines are fairly easy to get sounds for provided a complete skull is present. As for the biome... ![]() That's how it'd probably have looked. Distinct wet-dry seasons, probably a warm but mild climate, perhaps considered subtropical. Temperate rainforest or just temperate would do fine. Edited by Incinerox, Feb 23 2015, 06:10 PM.

A little off topic but why even bother asking the question if you seem to already have known the answer? Also, is there any evidence to directly indicate symbiosis between certain paleo-life? |

AFAIK a queen flying ant that was carrying an aphid with her jaws was preserved in ambar suggesting that the Aphid-Ant simbiosis existed already during the Miocene or earlier.

Pyroraptor wasn't from Hagteg Island. It was from France. Also Bradycreme and Elopteryx were troodontids so they were more of the generalised omnivore then a carnivore. |

Plus it's thought by some that Bradycneme was an alvarezsaurid, which would probably make it an INSECTIVORE. |

The mosasaur body plan was far more hydrodynamic and energy efficient. Same reason why whales are the dominant marine mammal today and not pinnipeds. Except pinnipeds have both the luxury of agility and the capacity to move on land. |

It is worth mentioning that the dissapearance of Pliosaurus both in the North and South Hemisphere seems to have took place at the end of the Cenomanian, more or less at the same time as: - Ichtyosaurids went extinct. - Spinosaurids went extint. - Modern Lamniform shark diversified with some of the becoming bigger than modern Carcharodon. - The first very basal and probably amphibious mosasaurids appeared. Call me crazy but I don't think that a coincidence, for me it either means that: - There was a massive enviorimental change across the marine and coastal envioriment across the globe that caused the extinction of Pliosaurids and Ichtyosaurids with Lamniformes, Basal Mosaurids and Polycotylidae plesiosaurids rushing to fill the void. - That Lamniformes (and Polycotylidae in the case of Ichtyosaurids) somehow managed to outcompete both of them, probably also with the help of an enviorimental change that favoured them due to the fac that they probably didn't need as much food as their reptilian competitors (not sure why Polycotylida did it through while Ichtyosaurids didn't) . Anways once large Mosasaurids arrived to the scene they end out displacing the large Lamniformes with Cretoxyrhina and some of it's relatives vanishing from the fossil record at the start of the Campanian and beign subtituted with smaller morphs like Squallicorax until the K/Pg event (in which the fact that Lamniformes probably needed less biomass to survive than Mosaurids and other marine reptiles played a big role in the fact that they survived).

Speaking of how Icthyosaurs went extinct.... I have wondered for sometimes what actually happened to them. One theory said that Icthyosaurs faced their doom due to the replacement of new group of fish that outcompeted the old ones that Icthyosaurs used to hunt and the change of the prey make them went extinct.... However, how can such issue made one of the most adapted and most hydrodynamic sea reptiles reaching the end of their day? It isn't likely that they won't be able to hunt new kind of fish... Any opinion on this? |
