Here's the new Nigersaurus next to the original from 2018. Main difference is probably the head posture which now reflects studies since 2018.

Dinovember Glow Up #3 - Nigersaurus

Day 3! Let's give it up for Day 3! And today’s glow up goes to Nigersaurus, here pausing from grazing horsetails to check if it really did see a predator watching it.

A Nigersaurus turns to face its' right, its' mouth full of horsetails.

Here is the new Pachyrhinosaurus compared with the original from 2018. Much happier with the new one's colour scheme.

Dinovember Glow Up #2 - Pachyrhinosaurus

Today's piece is a lone Pachyrhinosaurus out for a stroll. It feels good to draw this dino again after a long time; the nasal boss was much easier to draw this time.

Surprise, more Kem Kem theropods! Here's a small indeterminate noasaurid, between 2-3m long, known from fragmentary remains. With smaller animals, I am drawn to vivid colours and flashier displays - like the speculative skin flap on the tail. Size comparison below ⬇️

Small noasaurid - it has dark green fuzz on the front half of its body adorned with teal, white, yellow, and orange stripes. On the tail, these colours are mirrored.

Xericeps is another fragmentary Kem Kem pterosaur, known from a distinctively curved lower beak, complete with interesting protrusions on the inside, much like Alanqa - this speculative reconstruction is based loosely on the modern openbill stork!

Size comparison below ⬇️

An unusual high-spined dinosaur from the Kem Kem, it's Spinosau- oh wait, it's Rebbachisaurus, a medium-sized diplodocoid sauropod. I based much of this reconstruction on related species, such as Lavocatisaurus and Limaysaurus. Size comparison below ⬇️

Back underwater, we find the Kem Kem's resident freshwater plesiosaur! This animal is known from a couple adult specimens and one youngster. Size comparison below ⬇️

Back to the Kem Kem series! Taking to the air once more with Anhanguera - a piscivore with a 4-5m wingspan, and the first toothed pterosaur in the lineup. Size comparison below ⬇️

Next up, Elosuchus! This animal is not a crocodile, but sits on another branch of the family tree along with its much more famous cousin Sarcosuchus - the pholidosaurs. Size comparison below ⬇️

Next on the list, and one of two incredibly obscure ornithischians from the Kem Kem, an indeterminate iguanodontian! This animal is only known from a singular half-metre-long footprint. More thoughts and size comparison below ⬇️

Really venturing out of my comfort zone for this next critter in the Kem Kem series - a fish! This is Axelrodichthys, a giant mawsoniid coelacanth with a potential upper length of 4m. Size comparison below ⬇️

Here is the tenth in the Kem Kem lineup - we're taking a break from pterosaurs to meet the largest animal in the ecosystem, a gargantuan titanosaur known from enormous trackways and fragmentary fossils. Size comparison (gulp) below! ⬇️

I am so much more comfortable drawing pterosaurs when they're on the ground. Here's Apatorhamphus, another one of the larger Kem Kem pterosaurs, alongside Alanqa, with a possible 7m wingspan. Size comparison below ⬇️

I so rarely draw pterosaurs in flight. Here's Afrotapejara, another Kem Kem pterosaur known from some beak material. Tapejarids must have been some of the oddest of the pterosaurs - and that's saying something! Size comparison below ⬇️

I'm surprised I've managed to keep this series going almost daily. Anyways, here's the next Kem Kem pterosaur - the tiny probe-feeder Leptostomia! As always, size comparison below ⬇️

Moving on from theropods, we now look at the pterosaurs of the Kem Kem, beginning with the azhdarchoid (?) Alanqa! Some thoughts and size comparison below ⬇️

I'm in a Kem Kem mood it seems. On the other end of the spectrum from the lithe and lanky Deltadromeus is the stocky and robust Carcharodontosaurus! Size comparison below ⬇️

One of my favourite theropods, and one of the most enigmatic - the giant Deltadromeus from Cenomanian North Africa. More thoughts and a size comparison below ⬇️

If you get an influx in notifications on here it will probably because I finally found them on here haha
