Chronotex field observations

Huge adult Alamosaurus range over vast areas in search of food, but several regularly return to the lake near TimeBase 67 to bathe and drink. This animal’s proportions are all ‘upfront’ in appearance – it looks as though it’s almost going to topple over. However, these dinosaurs aren’t in any way particularly inflexible or of limited mobility.

No predator, not even Tyrannosaurus, would tackle a mature adult. Its tail has no spikes or clubs but is so heavy that it’s used in defence, and other dinosaurs stay clear of its striking range. In fact, despite the ‘gentle giant’ stereotype, Alamosaurus can display an aggressive streak, and it’s unafraid to intimidate or tackle other dinosaurs, big or small.

Alamosaurus teeth are found all over the plains outside the facility, since they only have a lifespan of approximately one month before being shed and replaced. We’ve also recorded this animal eating eggs, carrion and small animals on occasion – although they may have been eaten accidentally.

Key facts

  • Gigantic, long-necked herbivore and one of the biggest sauropods of all time
  • North America’s last sauropod and possibly an invader from South America (where sauropods were more abundant)
  • Slender, narrow-crowned teeth well suited for cropping leaves, fronds and plant materials of all time
  • Eats hundreds of kilos of food a day, digesting plant material virtually all the time – therefore regularly producing huge quantities of dung
