Deep in a Cretaceous jungle where dinosaurs roam free, this primitive bird is stretching its wings while perched on a mossy tree branch. It’s probably one of the Enantiornithes, which thrived throughout the Cretaceous Period before becoming extinct along with all the non-avian dinosaurs. 14 more words

Oh my, how time flies. When life get’s in the way, it keeps on getting.
These last few month I have been so preoccupied by other projects, museum- and research-wise, that by now, I am pretty sure, most of you have simply checked Mary Annings wiki-page to find out how our palaeontology super-heroine story ends. 820 more words
Yehuecauhceratops mudei was a ceratopsian dinosaur that roamed Mexico around 72 million years ago, during the late Cretaceous period. Though known only from fragmentary remains, these are enough to show it was relatively small, with a length around three meters (or less than ten feet). 21 more words
Fish in a Jurassic river go about their routines around the feet of a wading sauropod dinosaur (I had in mind one of the brachiosaurs). Although the old belief that sauropods would have been primarily aquatic has been discredited for the most part, I’m sure they occasionally waded or swam across water, either to get from place to place or to cool off under the intense Mesozoic heat.
Just as the animal kingdom lost some remarkable designs during the mass extinction events that punctuated the Palaeozoic and Mesozoic (consider the disappearance of the novel carapaces of trilobites and the aerofoils of pterosaurs), so too the plant kingdom lost some majestic groups that, had they survived until today, would no doubt have been cultivated as centrepieces in many domestic gardens. 1,738 more words
