In Depth When described in 2015, Probrachylophosaurus made headlines around the world, when it was often dubbed ‘superduck’. This was because Probrachylophosaurus was proposed to be the transitional link between the non-crested genus Acristavus, and the later Brachylophosaurus which has a flat paddle shaped bony crest. Probrachylophosaurus itself has a much smaller triangular crest which … Read more

In Depth Tethyshadros is without doubt one of the more interesting genera of hadrosauroid dinosaurs. For a start hadrosauroids are not particularly well known from Europe, though large ornithopod dinosaurs which were ancestral to them are. Tethyshadros also seems to have been a dwarf hadrosaur, growing to an average length of four meters. This reduction … Read more

In Depth The first Brachylophosaurus remains were discovered in Alberta in 1936, but were not named until 1953 when Charles Sternberg made the description. A second species of Brachylophosaurus was named as B. goodwini by Jack Horner in 1988; however the wider consensus today is that these individuals are actually further individuals of the genus … Read more
