Latest Cretaceous megaraptorid theropod dinosaur sheds light on megaraptoran evolution and palaeobiology - Nature Communications Megaraptoran theropod dinosaur anatomy and evolution is unclear due to the fragmentary nature of most available fossils. Here the authors report a well-preserved, late surviving megaraptoran from Argentina that clarifies our understanding of the morphology of this group and potentially provides insights into its diet and feeding strategies.

A newly discovered species of South American predatory dinosaur, called Joaquinraptor casali, is described in @natcomms.nature.com. It dates to the latest part of the Cretaceous Period between approximately 70 to 66 million years ago: www.nature.com/articles/s41...

The oldest known lepidosaur and origins of lepidosaur feeding adaptations - Nature A rhynchocephalian skeleton around 3–7 million years older than the oldest currently known lepidosaur fossil provides important insight into the origin of lizards and snakes.

A tiny lizard-like fossil from Devon, UK, dating to around 244–241.5 million years ago, may now be the oldest known member of the group of reptiles known as lepidosaurs. The discovery helps to resolve a debate about reptile evolution and sheds light on the origins:

Extreme armour in the world’s oldest ankylosaur - Nature The ankylosaurian dinosaur Spicomellus afer possessed a tail weapon and uniquely elaborate dermal armour.

Earliest known ankylosaurs had uniquely elaborate body armour, including a spiky ornament on their tail. These extreme armour features are unlike those of any other vertebrate, including other ankylosaurs later in their evolutionary history: spklr.io/63322BHH8j

advice needed! this 15,000 y.o carving is the oldest example of insect art. the middle-top shows a cave cricket, my study group, and i'd love to get it as a tattoo. one problem: how do i avoid it looking poorly done when best reconstruction i can find looks like this? 🤨 #bugsky #palaeosky

A haplotype network of African buffalo mitogenomes.

It doesn't look like the divergent mitogenome came from any other extant buffalo population, so we think it is the result of breeding between ancient populations of African buffalo and one of two extinct species - the giant long-horned buffalo (Syncerus antiquus) or S. acoelotus. #palaeosky

I urgently need some help from #palaeosky
I've been using rgeos for a while to reconstruct plates and recently realised the package didn't make it to the latest R update. What can I use now to use "reconstruct" in R?
