CLICKBAIT, ROUND 3: Time to Rant.
Note: I deleted this post last night due to a ridiculous amount of hateful private messages and comments. Here it is again, edited down.
The closest modern relatives of theropod dinosaurs (such as the 66 million year old “Tyrannosaurus rex”) are the birds that fly amongst the skies today. Over 165 million years of evolution separates “Tyrannosaurus rex” to a chicken; the earliest birds began diverging in the mid Jurassic. It’s true, from a cladistics point of view, that birds are technically dinosaurs! But a spectacular amount of time separates these two groups; the direct descendant of bats, whales and even humans was around some 66-70 million years ago. This post gives the impression that Tyrannosaurus rex EVOLVED into a chicken. This is COMPLETELY FALSE and not how evolution and natural selection works AT ALL... Like all non-avian dinosaurs, the Tyrannosaurs were obliterated 66.03 million years ago when a bright fireball in the sky slammed into earth. All birds (from ducks and geese, to large ratites such as ostriches and moas and even eagles and pigeons) come from one single grouping of birds just before the K-T boundary extinction event.
What is most concerning about this post is the absurd coverage. Almost 20,000 likes, along with a quarter of a million people following this page. This is clickbait BS. Imagine what you could say to a quarter of a million people. What would you say? It’s our duty as scientists and science communicators to tell EVERYONE that we are in the midst of the worst extinction event EVER, and yet we are still arguing about the existence of manmade climate change in parliaments worldwide. It’s happening. The lives of animals that have been around for hundreds of millions of years are facing their worst extinction threat yet: politicians unwilling to understand the critical science behind anthropogenic change…

A fossil brittle star preserved in the process of regenerating it's arms! Brittle stars are so named because of the tendency for their arms to break off (as a defence). Their arms can also be lost by predators nipping them off. Fortunately for brittle stars they are able to grow their arms back, though this process is not captured especially often in the fossil record. The new Chalk echinoderm assemblage that we are working on is unusual in this regard as specimens with regenerating arms are common place. The example shown here displays multiple regenerating arms and evidence for multiple 'attacks' in the time prior to its death. Swipe across to see arrows highlighting the regeneration points and a modern example for comparison.
Ophiotitanos tenuis, Late Cretaceous Grey Chalk of Southern England, around 96 million years old.
Being a bit cheeky and touching the exhibit but I absolutely loved the dinosaurs in the Kirstenbosch national botanical gardens in Capetown. Dinosaurs were what first drew me to geology and even though I'm now down rather a different branch of geoscience they're still very special to me. Don't let anyone tell you dinosaurs are just for 12 year olds, there's nothing wrong with being excited by a group of animals that dominated the earth for much longer than we have or likely ever will 🦖🦖🦖 #geologistsofinstagram #geology #geoscience #geologist #dinosaur #southafrica #capetown #palaeontology #mininggeology
I have an intense need for this. 😍😍
Just a quick test of the new dust extractor with air abrasive and this sticky Promicroceras sp. ammonite in a small scrap of limestone. Figured I'd also see if I could get some time-lapse footage as well. Didn't take long at all to clean this ammonite, in fact it took longer to create the 'bowl' around the outside edge! Air abrasive isn't the 'be all and end all' of fossil preparation but it does have its place. It can often help with ammonite preparation when the shell doesn't want to come away from the calcite mould underneath, and at times when the surrounding rock doesn't want to come away from the shell. Its main use is for applying finishing touches or careful removal of material too small to remove with air chisels. There wasn't a great deal of covering material on this ammonite, which made it very quick to prepare but the majority of fossils take much, much longer on average. Approximately 195 million years old and found at Charmouth, Dorset.

Revealing the rich geological story that lies beneath the Jurassic Coast! The present day landscape reflects the varied rock types which underlie it and a deep-rooted structural framework of faults and folds. The faults provide zones of weakness where river valleys can form, whilst hilly areas occur where the more resistant rock formations outcrop at the surface. I'll aim to present more on how this fascinating region was formed and the wider Earth-story context in subsequent posts…
