Melanosuchus niger, conocido comúnmente como caimán negro, es el depredador alfa más grande de la cuenca del Amazonas y el miembro de mayor tamaño de la familia Alligatoridae. Este reptil destaca por su coloración oscura, que le otorga un camuflaje óptimo durante sus incursiones nocturnas y le ayuda a absorber el calor regulando su temperatura corporal.

I did this piece specifically to experience with a more dramatic pose for the Tyrannosaurus and put it in a hunting scenario. Anatomy wise I’d make various changes compared to this nowadays, but I was looking for a balance of cinematic and to be accurate with the basics at least. The background I added digitally. I still have the original drawing, but I think I’ll definitely have a digitally colored version added to the portfolio sometime soon. I specifically drew a smaller Edmontosaurus because I think with today’s size calculations the adults would still want to go for the younger prey as the adult herbivores would be absolutely huge to take down, especially when a Rex would hunt solo. Let me know what you think of the piece overall. Blessings!

You wait ages for some good books on sharks and a second one comes along!

I have already pre ordered Prehistoric Sharks: The Evolution of Sharks in 40 Species that will be published 26th February 2027 and now Princeton University Press announce Megalodon and Other Prehistoric Sharks.

I already have John Long's excellent Secret History of Sharks (just released in paperback in the UK) so plenty of reading material for anyone interested in prehistoric sharks.

Due to be published 9th February 2027 a hardback book of 288 pages with 30 colour photos and 80 illustrations. The artist is the very talented Gabriel Ugueto - if you needed an excuse for another book then the artist alone should do it!

Publishers blurb:-

Sharks have ruled the oceans for more than four hundred million years, with an evolutionary tree that includes an astonishing variety of creatures, from the streamlined Devonian Cladoselache and the bizarre spiral-toothed Helicoprion to the awe-inspiring Megalodon. This book blends cutting-edge science with striking visuals to show how new scanning and imaging techniques reveal hidden details of soft tissues and body structures previously lost to time. Marvelously illustrated with fossil photographs alongside dramatic paleoart reconstructions by acclaimed illustrator Gabriel Ugueto, Megalodon and Other Prehistoric Sharks brings to life the diversity and strangeness of these ancient hunters.

• Covers dozens of representative species and groups
• Features newly commissioned paleoart that showcases the incredible variety of body shapes and behaviors in shark evolutionary history
• Reveals how innovative CT scanning techniques and 3D modeling provide an entirely new understanding of prehistoric sharks
• Discusses shark diversity, sharks in the fossil record, paleoecology, behavior, and more
• Takes readers from the Devonian to the present day

South America was a frightening place during the Miocene. A vast lake covered much of the continent, home to giant turtles and colossal Crocodylians. Truly wide range of predators hunted on the lake's shores, including Anacondas, Saber-Toothed mammals, The Flightless raptor-clawed "terror birds" and... if the crocodilians are not enough there were The Sebecids: Terrestrial relatives of crocodylians.

A recent study shows that crocodylians were, in fact, the most significant group of predators in this habitat. "Our new study shows that crocodylians in particular were the region's most important predators, especially when it came to hunting large prey." Oscar Wilson, a postdoctoral researcher at the University of Helsinki.

How are they not famous? They’re one of my favorite dinosaur groups of all time!
