The authors discovered that the fish's conical 'fangs' in the upper jaw pointed sideways, not downward like sabers, helping us better understand the behaviors and morphology of this fascinating extinct fish. (Figure from Claeson 2024).

We LOVE 💕 Ray's depiction of Oncorhynchus rastrosus, the giant spike toothed salmon, created for their 2024 scientific paper. [THREAD ⬇️]

Believe it or not, this photo shows 📸 the same sex and species, but the one on the bottom is in its spawning phase of life!

Male salmon develop a hooked bottom jaw called a "kype" and form a hump on their back along with drastic color changes and MORE. Both sexes ♂️ ♀️ undergo change.

Would you believe within mere WEEKS 🗓, the skull of a Sockeye salmon (Oncorhynchus nerka) will DRASTICALLY change morphology, or shape? [THREAD ⬇️]

Fun fact: The T. rex on the mural’s left side influenced the design of Godzilla, the atomic-powered sea monster that made its motion picture debut in 1954.

📍Want to see it for yourself? You can view the mural now at the Peabody Museum in New Haven, Connecticut.

The work earned Zallinger the 1949 Pulitzer Fellowship in Art. In 1953, Life magazine published the entire painting in a foldout.

The painting depicts 32 dinosaur species spanning 362 million years. It begins with the origin of land vertebrates during the Devonian Period and ends with the dinosaurs’ extinction during the Cretaceous era.

It was executed using the fresco‑secco method—a Renaissance‑era technique involving pigments mixed with egg 🥚 and water 💧 applied onto dried plaster—this approach allowed for remarkable detail and durability.

Are you familiar with Rudolph Zallinger's magnificent "Age of Reptiles" mural?

This 110 ft long fresco mural 🎨🖌 was completed by Zallinger in 1947 for the Yale Peabody Museum after five years of work.

What’s even cooler? The lophophore is shaped like a U, forming what look like little arms 💪—called brachia (that’s where "brachiopod" gets its name!). So basically, these ancient sea creatures are like underwater royalty, waving their arms to scoop up snacks from the sea.
Ep #89 Brachiopods Deserve Your Love | Paleo Nerds
Ray and Dave learn all about Brachiopods, one of the hardy survivors of the Big Five extinctions, with Susan Butts, Director of Collections and Research at the famous Yale Peabody Museum.

Be a brachiopod this Labor Day weekend! RELAX and let the food 🍔🌭 come to YOU!

Brachiopods have a built-in filter called a lophophore (LOW-fo-four). Tiny tentacles covered in super-fine hairs called cilia whip up the water, pulling in food like a vacuum cleaner.
