Stegosaurus build - what went wrong?

Every other dino archetype survived to the KT boundary. Hadrosaurs (duck bills), ceratopsians, large Sauropods, raptors, large Theropods (tyrannosaurids) all survived until the meteor hits. Stegosaurids died out in the Jurassic.

      Still doesn't survive to KT boundary like other builds

    they disappeared about the same time cycads died out.

    >Stegosaurids died out in the Jurassic
    nope.
    there's plenty of evidence they survived right up to the K-Pg boundary.

      Overreliance on cycads.

      Though Late Cretaceous stegosaurian fossils have been reported, these have mostly turned out to be misidentified. A well-known example is Dravidosaurus, known from Coniacian fossils found in India. Though originally thought to be stegosaurian, in 1991 these badly-eroded fossils were suggested to instead have been based on plesiosaurian pelvis and hindlimb material,[32] and none of the fossils are demonstrably stegosaurian.[33] The reinterpretation of Dravidosaurus as a plesiosaur wasn't accepted by Galton and Upchurch (2004), who stated that the skull and plates of Dravidosaurus are certainly not plesiosaurian, and noted the need to redescribe the fossil material of Dravidosaurus.[34] A purported stegosaurian dermal plate was reported from the latest Cretaceous (Maastrichtian) Kallamedu Formation (southern India); however, Galton & Ayyasami (2017) interpreted the specimen as a bone of a sauropod dinosaur. Nevertheless, the authors considered the survival of stegosaurians into the Maastrichtian to be possible, noting the presence of the stegosaurian ichnotaxon Deltapodus in the Maastrichtian Lameta Formation (western India).[2]

    We still don't know what their stupid plates were used for? The prime theory was heat dissipation. Sounds lame, no?

      Who gives a duck what they were used for? They look fricking cool, that's all I want

      Heat dissipation was the standing theory until about 4 years ago but some of the more recent models indicate that is may have stored a fatty mass similar to a camels hump with the spines acting as supports to stop the hump rolling offside.

      So yeah, it turns out that stegs may just be big camels and those spines were 'internal'.

        moronic. doesn't make sense with plate shape and how they're attached to the body. why would they even store fat up on their weak fricking back and hips anyway?

          We know they were on the back, but no one is sure how they were really carried.
          I'd be skeptical of the hump angle just because those big street sign shaped plates weren't the only kind there were, some had spikes, some were moronic nubbins, some were different shapes. I wouldn't expect to see that kind of variation for an internal structure.
          If they're for display purposes it makes sense to see that kind of variation.

            the thread is mostly lying. We know they were used for defense because we've found one with a bite taken out of it. A bite that healed because the animals survived the attack. It survived the attack because the plates were effective for defense.

            that doesn't rule out other possible uses, but we know the main one.

              They were used as serving trays and one day Fred Flintsone was really hungry for his Bronto-Burger and took a generous chomp out of the stego on accident.

      If an animal has some really stupid and garish thing stuck to their body with no real apparent use the answer is ALWAYS sex

    They got hunted to extinction for their dorsal fins (used in traditional medicine as an aphrodisiac)
