Two archosaurs (diapsids) enjoyed the sun while this mammal (synapsid) enjoyed watching them. But hey—we are all tetrapods. #phylogeny #tetrapods #archosaurs

Unlike a solid sea wall, which takes the full, brutal "punch" of a wave, these structures use a "jujitsu" approach to water.

Mazon Monday #309: Herbivory is Older Than We Thought! This is Mazon Monday post #309.  What’s your favorite Mazon Creek fossil?  Tell us at  email:esconi.info@gmail.com. The Mann Lab at the Field Museum has been very busy. Their new paper "Carboniferous recumbirostran elucidates the origins of terrestrial herbivory" published in the journal Nature Ecology & Evolution has significant implications for the Mazon Creek ecosystem. This paper shows how even "old" ecosystems like the Sydney Mines and Mazon Creek are constantly being reinterpreted through new discoveries.

Mazon Monday #307: Arjan Mann on Fossil Nerds This is Mazon Monday post #306. What’s your favorite Mazon Creek fossil? Tell us at email:esconi.info@gmail.com. Episode #94 of the Fossil Nerds podcast is "The Marvelous Mini-Monsters of Mazon Creek with Arjan Mann". Arjan is the Assistant Curator of Early Tetrapods at the Field Museum. He discusses his lab's work, various ancient fish and tetrapods, gorganopsids, and (of course!) Mazon Creek.

Tiktaalik slugs its way over a muddy bank in a flooded Devonian landscape while the sun sets over the horizon. Banks of pink and purple clouds loom in front of distant streaks of orange as clear turquoise sky peeks through cloudless regions. Various trees and shrubs stand tall above purple water glistening with gold wavelets. With vision that could probably see in the UV spectrum and eyes beginning to adapt for the infinite visual range provided in aerial habitats, Titaalik pauses to take this all in, being among the first animals that can see the natural world in such detail. All which is to say - the next time you admire sunsets or the night sky, consider what this owes to events of 375 million years ago. When the first vertebrates struggled out of the water they rapidly developed eyes that were much sharper and clearer than those of their fishy ancestors, vision being of variable utility in most freshwater habitats. Millions of years on, what probably started as a means to navigate and find prey allows us to observe and enjoy the natural world with a sense of awe and wonder.

New #paleoart on #FossilFriday: #Tiktaalik sees the world. Discussions of early #tetrapods often focus on limbs and lungs, but major changes also took place in their eyes. Seeing further and clearer than any animal before, they were the first to clearly see sunsets, stars, and the moon. #sciart

Variety of animals evolved similar genetics solutions to survive on land, study finds Animals from completely different branches of the tree of life such as insects, worms and vertebrates independently evolved similar genetic solutions to survive on land, according to a new study from researchers at the University of Bristol and University of Barcelona.

PBS Eons: When We Left The Water (By Accident) PBS Eons has a new episode. This one is about when tetrapods moved from the water onto land... It’s beginning to look like our success on land, and that of all tetrapods, from frogs to dogs to dinosaurs, was just a lucky side-effect of fish trying to stay fish.

Aistopods were a group of enigmatic, likely aquatic tetrapodomorphs (possibly tetrapods) that were one of the first cases of a complete legless condition among tetrapodomorphs

Earliest reptile footprints rewrite the timeline of tetrapod evolution New discoveries of fossil clawed footprints from Australia, published this week in Nature, push the origin of reptiles back in time by at least 35 million years and change the entire timeline for the origin of tetrapods (backboned land animals).

The #Walton #Lighthouse in #SantaCruz, CA. Also, a closer look at the massive #tetrapods that help prevent the erosion of the breakwater. During storms, waves may wash over the jetty and splash over the top of the lighthouse.

The #Walton #Lighthouse stands near the end of a #breakwater next to the waterway leading to the yacht harbor in #SantaCruz, CA. The breakwater has been shored up with 40-ton interlocking and wave-dissipating concrete structures called #tetrapods.

If these tracks really are from a sauropsid amniote then not only does that push back the origin of amniotes, it also suggests much more rapid evolution of terrestrial #tetrapods in the Devonian.
