What was the largest herbivore in the time of the dinosaurs?
William Borde
The largest dinosaur herbivore – and the largest herbivore of all time – was a sauropod named Argentinosaurus. As the name suggests, its remains have been found only in Argentina. No complete skeleton has ever been discovered, but individual backbones from Argentinosaurus are over 1.5 metres tall – taller than many adult humans. It has been estimated that a fully grown Argentinosaurus would have weighed over 70 tonnes, more than ten fully grown African elephants. Several ideas have been proposed to suggest why sauropods got so large, including the need for very large digestive systems to deal with tough, fibrous plant food.
WHICH METAL HAS THE HIGHEST MELTING POINT?
Lei Smith
Tungsten, often referred to as wolfram in other parts of the world, has the highest melting point of any metal. Extracted from wolframite, scheelite and other minerals, it is a grey-white metallic element and is incredibly dense and extremely hard. In fact, it is the second-hardest material – only beaten by diamond – has a greater density than lead and does not break down or decompose, meaning it’s also environmentally friendly. This range of properties means that tungsten is used in many industries and products, from high-speed cutting tools and jet turbine engines to
