This suggests ankylosaurs had complex behavior, possibly battling for <a href=\"https:\/\/buradabiliyorum.com\/en\/category\/social-mediaa\/\" data-internallinksmanager029f6b8e52c=\"1\" title=\"Social Media\" target=\"_blank\" rel=\"noopener\">social<\/a> and territorial dominance or even engaging in a &#8220;rutting&#8221; season for mates. The research is published in the journal <i>Biology Letters<\/i>.<\/p>\n<p>The 76-million-year-old, plant-eating dinosaur, part of the Royal Ontario Museum&#8217;s vertebrate fossil collection, is named after the fictional monster &#8220;Zuul&#8221; from the 1984 movie &#8220;Ghostbusters.&#8221; Initially the skull and tail had been freed from the surrounding rock, but the body was still encased in 35,000 pounds of sandstone. After years of work, the body was revealed to have preserved most of the skin and bony armor across the entire back and flanks, giving a remarkable view of what the dinosaur looked like in life.<\/p>\n<p>Zuul&#8217;s body was covered in bony plates of different shapes and sizes, and the ones along its sides were particularly large and spiky. Interestingly, the scientists noticed that a number of spikes near the hips on both sides of the body were missing their tips, and the bone and horny sheath had healed into a blunter shape. The pattern of these injuries was more consistent with being the result of some form of ritualized combat, or jousting with their tail clubs, and probably wasn&#8217;t caused by an attacking predator like a tyrannosaur because of where they were located on the body.<\/p>\n<p>&#8220;I&#8217;ve been interested in how ankylosaurs used their tail clubs for years and this is a really exciting new piece of the puzzle,&#8221; says lead author Dr. Victoria Arbour, Curator of Paleontology at the Royal BC Museum and former NSERC postdoctoral fellow at the Royal Ontario Museum. <\/p>\n<p>&#8220;We know that ankylosaurs could use their tail clubs to deliver very strong blows to an opponent, but most people thought they were using their tail clubs to fight predators. Instead, ankylosaurs like Zuul may have been fighting each other.&#8221;<\/p>\n<ul class=\"article-gallery js-article-gallery\">\n<li data-thumb=\"https:\/\/scx1.b-cdn.net\/csz\/news\/tmb\/2022\/ankylosaurs-battled-ea-1.jpg\" data-src=\"https:\/\/scx2.b-cdn.net\/gfx\/news\/hires\/2022\/ankylosaurs-battled-ea-1.jpg\" data-sub-html=\"Zuul crurivastator photo and illustration with injured spikes marked in red.

The back half of the tail was stiff and the tip was encased in huge bony blobs, creating a formidable sledgehammer-like weapon. <\/p>\n<p>Zuul crurivastator means &#8220;Zuul, the destroyer of shins,&#8221; a nod to the idea that tail clubs were used to smash the legs of bipedal tyrannosaurs. The new research doesn&#8217;t refute the idea that tail clubs could be used in self-defense against predators, but shows that tail clubs would also have functioned for intra-species combat\u2014a factor that more likely drove their evolution. Today, specialized animal weapons like the antlers of deer or the horns of antelopes have evolved to be used mostly for fighting members of the same species during battles for mates or territory.<\/p>\n<p>Years ago, Arbour had put forward the idea that ankylosaurs might have clubbed each other in the flanks, and that broken and healed ribs might provide evidence to support this idea. But ankylosaur skeletons are extremely rare, making it hard to test this hypothesis. The completely preserved back and tail of Zuul, including skin, allowed for an unusual glimpse into the lives of these incredible armored dinosaurs.<\/p>\n<ul class=\"article-gallery js-article-gallery\">\n<li data-thumb=\"https:\/\/scx1.b-cdn.net\/csz\/news\/tmb\/2022\/ankylosaurs-battled-ea-2.jpg\" data-src=\"https:\/\/scx2.b-cdn.net\/gfx\/news\/hires\/2022\/ankylosaurs-battled-ea-2.jpg\" data-sub-html=\"Injured and healed spike from Zuul's left side.
