In late January 2026, the blog Tetrapod Zoology will be a ridiculous 20 years old. I'll be putting out a long introspective article but am still thinking I should arrange other events. Here are just a few images from the blog's history of operation...

Dinosaurs like Diplodocus may have been as colourful as birds
Skin fossils from a sauropod dinosaur examined with an electron microscope feature structures called melanosomes, which are similar to those that create the bright colours in birds' feathers

A somewhat liberal interpretation, but definitely inspired by your study! The amount of details of past life preserved in the fossil record never ceases to amaze me. Nor does the creativity and tenacity of paleontologists, working to tease out that information. What a cool study!

Analysis of Diplodocus skin fossils indicates the presence of diverse melanosome types, suggesting these dinosaurs may have exhibited speckled color patterning rather than uniform coloration.

Analysis of Diplodocus dinosaur scales reveals possible speckled color patterning
Scientists have long been trying to reconstruct the appearance of dinosaurs. The tidbits they are able to piece together from fossils and other analysis are displayed in museums, educational materials, and media, lending to our idea of what these ancient creatures looked like.

The jumble of bones looked like porridge. It turned out to be a new species of pterosaur preserved in prehistoric vomit, the latest fossil find extracted from dinosaur excretions. I’ll tell you more in my latest for NatGeo. 🧪

There were so many big paleo publications made this year, especially in the last few months. First sauropod with gut content, nanotyrannus X2, new hadrosaur mummies, new pterosaur in vomit. You think any more big things will come before the year ends????

Even dinosaurs slipped sometimes. This cast was made from a hadrosaur track found in 80 million-year-old rocks in Utah. Once considered the biggest hadrosaur track, it just looks extra large because the dinosaur’s heel slipped as its foot touched the ground. 🧪

Oh, you haven’t seen the last of Nanotyrannus. A new study, overlapping with the big paper a few weeks ago, may add to the evidence Nanotyrannus is back. I’ll catch you up on my latest for National Geographic. 🧪

Nanotyrannus likely was a tiny adult dino and not a teen T. rex
Short king confirmed? Together with a blockbuster October study, a new throat bone analysis delivers a “one-two punch” to the 40-year debate over whether Nanotyrannus lancensis was a distinct species.

What might be my favourite fossil has been just published by Kiat et al. 2025. Years ago I saw a pic of this Anchiornis specimen in nat geo article and I audibly gasped.preserving not only the feathers but also the original patterns as well. I made this drawing on the spot. Maybe its time to do v2.0
