Dinos ‘too successful for their own good’

  Dinos ‘too successful for their own good’ A study modelling how dinosaurs spread worldwide shows they may have been a victim of their own success. UK researchers believe they were already in decline before the killer asteroid hit because they had occupied every habitat on Earth.From their roots in South America, the dinosaurs migrated "in a frenzy of movement to cover the planet".Hundreds of different dinosaurs appeared, from the ferocious T. rex to the gigantic long-necked Diplodocus.But by the time the asteroid struck, killing them off, they were starting to decline, as they had ran out of space on Earth.

They also discovered the horns and frills seemed to evolve much more quickly than others. Big and burdensome, the embellishments are costly to grow and The study builds on previous research suggesting one horned dinosaur —protoceratops—may have evolved frills under sexual selection.

Triceratops are famed for the huge bony frills and horns on their heads. But why do the gentle giants wear such imposing accessories?

Scientists used to think this armor helped the huge herbivores avoid cross-species breeding. Now, evidence points to a different explanation: sexual selection—the horns and frills were built to attract, not repel, suggests research published in Proceedings of the Royal Society B.

Different species roaming the same ground may evolve features to tell each other apart, preventing them from breeding across species lines and giving birth to unfit offspring. Researchers wanted to know if this was behind the extravagant frills and horns of certain dinosaurs.

Rare dinosaur discovery in Egypt could signal more finds

  Rare dinosaur discovery in Egypt could signal more finds A skeleton has been unearthed in Egypt's Western Desert, whose ancient sands have long helped preserve remains, but unlike most finds this one isn't a mummy — it's a dinosaur.Researchers from Mansoura University in the country's Nile Delta discovered the new species of long-necked herbivore, which is around the size of a city bus, and it could be just the tip of the sand dune for other desert dinosaur discoveries.

It has been suggested that different species that live in the same location may evolve features

The team studied the patterns of ornamental horns and frills in 46 species of horned dinosaurs (ceratopsians), including the triceratops. They found no significant differences in these ornamental patterns between species that lived together and those that lived apart.

They also discovered the horns and frills seemed to evolve much more quickly than others. Big and burdensome, the embellishments are costly to grow and maintain. This, the researchers said, suggests a strong selective pressure.

The study builds on previous research suggesting one horned dinosaur—protoceratops—may have evolved frills under sexual selection. Now, researchers think this could be the case across the whole horned group.

Jurassic World Alive is Pokémon Go but with dinosaurs

  Jurassic World Alive is Pokémon Go but with dinosaurs  The monster hunting of Pokémon Go meets dinosaurs in Jurassic World Alive, a new augmented reality, location-based game for Android and iOS coming this spring. Developed by Ludia, which has previously worked on Jurassic World: The Game and Jurassic Park Builder, Jurassic World Alive will let players track, collect and do battle with dinosaurs. Jurassic World Alive puts players in the role of a new recruit in the Dinosaur Protection Group (DPG). Players are tasked with saving dinosaurs from another extinction by tracking them, collecting DNA samples and creating new hybrid species in a lab. Those man-made dinos can be assembled into a team and fight in player-versus-player arena battles, which kind of seems counterproductive to the whole dinosaur protection thing. In a press release, Universal and Ludia said players will track their Jurassic prey with a drone, and must track down supply drops in-game to earn in-game currency and battery life for that drone. Universal and Ludia are currently accepting registration for Jurassic World Alive on the game’s official website. Here’s a look at some screenshots of the game: Jurassic World Alive joins park simulation game Jurassic World Evolution and a trio of Jurassic World-themed tables for Zen Pinball on the list of tie-in games hitting alongside the next film in the franchise, Jurassic World: Fallen Kingdom.

"Modern computer models have suggested that sexual selection can promote rapid speciation, adaptation, and extinction,” Andrew Knapp, doctoral student at Queen Mary University of London and lead author of the study, said in a statement. "We have shown that species recognition, one of the commonest explanations, is unlikely to be responsible for the diversity or origin of ornamentation in this group."

Just like a peacock’s exquisite tail feathers, the frills and horns of a dinosaur are “advertising their quality or genetic make-up,” Knapp told the BBC.

Sexual selection might not be the only driver of horny ornamentation, Darla Zelenitsky from the University of Calgary, Canada, who was not involved in the study, told the BBC. “Some of these ornaments were also likely used at times for defence against predators or, to some extent, for recognition of members of different species, but these were apparently not the primary driver in their evolution."

If sexual selection is indeed behind ornament evolution in horned dinosaurs, this kind of research can help scientists figure out its effects across “potentially huge timescales," Knapp said.

“In our world of increasing pressure on the natural world,” he added, “These predictions may have important consequences for conservation and the fate of living things everywhere.
