Dinosaurs have hit the headlines recently with the finding of the partial remains of what may have been the largest dinosaur ever to tread the earth.

The ‘Rio Negro Giant’

Over the last year, researchers have unearthed, from an area in southern Rio Negro, Argentina, 20 gigantic fossilized bones that include two neck vertebrae measuring 117cm (3.84ft), plus femurs, ribs and tail bones. These have yet to be scientifically classified, so in the meantime the source creature has been named the ‘Rio Negro Giant’.1

Assuming that 10–12 vertebrae made up the neck, the researchers believe that the animal was a sauropod (see aside on sauropods below) that could have measured about 50m (165ft) from head to tail, towered about 14m (45ft), and weighed in excess of 10 tonnes.2 While this may have been the longest dinosaur ever found, it is not the heaviest; this record is held by the (estimated) 100-tonne Argentinosaurus, thought to have been some 8m (27ft) shorter than the Rio Negro Giant, but much bulkier.2

Claims of finding larger and yet larger dinosaur specimens are not unexpected—they are the ones most likely to make the news and attract research funding.3 However, the existence of such large dinosaurs is not contrary to the expectations of creationists. We believe that the dinosaurs show God’s marvellous creativity, so the larger the find,4 the more His power and majesty are revealed.

Sauropod eggs and embryos

Strange as it may seem, the gigantic sauropods did not lay gigantic eggs. Recently researchers found a site, also in Argentina, containing thousands of fossilized dinosaur egg fragments.5 The team recovered over a dozen eggs and 40 egg fragments that contained tiny teeth, fingernail-sized patches of delicate fossilized baby-dinosaur skin, and tiny collapsed bones, which have been identified as being from the embryos of sauropods.6 The eggs are round, 13–15cm (5–6 inches) in diameter, with an average shell thickness of 1.4mm (1/20th inch).6
