Spinosaurus drama is cool and things, but do you know what's even cooler? Better fossils of animals that lived with Spinosaurus!

There is a new specimen of Concavotectum currently on display in Tuscon. BigSkyFossils took some photos of it and I had to doodle it! It's been a while since I did a tselfatiform and now we have finally an idea how the postcranium looked like!

So far we only had a few fragments and this pretty good skull. As some people noted though, the eye is reconstructed in the wrong corner.

26" Fossil Fish (Knightia) Mass Mortality Plate

Don’t mess with this fish! For Fossil Friday, let’s meet Dunkleosteus terrelli. It lived some 360 million years ago during the Devonian. Scientists think it was one of the first large jawed vertebrates in the ocean and an aggressive predator. The razor-sharp edges of bones in its jaws served as cutters, and as they rubbed against each other, the opposing jaw blades acted like self-sharpening shears. These bones continued to grow as they were worn down by use.

This specimen, on display in the Museum’s Hall of Vertebrate Origins, was found in Ohio. Spot Dunkleosteus and other prehistoric animals at the Museum! Plan your visit.

Who do those spooky glowing eyes belong to!? Surprise! A coelacanth! Come adopt these spooky cuties before they go back into the deep deep sea!

The following is a digital doodle of a Allenypterus that I made. I did this as practice, I hope y'all like this drawing of this prehistoric Coelacanth.

Happy Fossil Friday!

Who: Coelacanthiformes

What: Coelacanths! Large lobe-finned fish from the Class Actinistia, a close relative of the lungfish.

When (group): Devonian - Present (thought to have gone extinct during the End-Cretaceous extinction event, but members of the group were "rediscovered" in 1938)

Where: (Living representatives) along the east African coast and the Comoros Archipelago in the Indian Ocean.

(Fossil representatives) England, Czech Republic, France, Germany, India, Switzerland, Brazil, Democratic Republic of the Congo, China, Uruguay, USA, and more.

Fun Fact!: There are two living speices (that we know of) of Coelacanth: Latimeria chalumnae & Latimeria menadoensis

Here is a link to an article for the story of how this "living-fossil" was rediscovered by the scientific community and the museum curator who's quick thinking and determination helped bring this animal back into the spotlight.

Why are they cool?: Instead of the bony vertebral column shared by other vertebrates the coelacanth retains the ancestral fluid filled notochord which is less rigid than vertebrae, but offers more flexibility.

#2830 - Megalampris keyesi

Named in honour of the New Zealand palaeontologist Ian Warwick Keyes (1938-2004).

New Zealand's largest fossil bony fish, twice the size of any of its living relatives, at over 4m long. It was found in the Otekaike Limestone, upper Duntroonian stage, Upper Oligocene (26 Mya).

Megalampris keyesi and the squalodontid-like dolphin Waipatia maerewhenua that I've discussed earlier, by Apokryltaros.

The living Opah species (Lampris) are deep-bodied fish of the open ocean found in warm and temperate waters worldwide. In May 2015, L. guttatus was found to keep its entire body at 5 °C above the surrounding water. The fish generates heat with continuous movements of its pectoral fins - the muscles are insulated by a one-cm-thick layer of fat - and heat-exchangers in the gills. This is very useful when in pursuit of fish, squid, and krill without that metabolic advantage.

How Fossil Fish Is Inspiring Creativity Across Millennia

Before modern science revealed their prehistoric origins, ancient peoples encountered fossil fish embedded in sediments and incorporated these mysterious remains into creative works, myths, medicines, and rituals. Across cultures and epochs, the recognizable shapes of fossils captivated imaginations and came to embody powerful symbolism in art, literature, architecture, and more. These paleontological muses continue to inspire creativity and culture today. Read more: https://fossilageminerals.hashnode.dev/how-fossil-fish-is-inspiring-creativity-across-millennia

okay i have done enough intensive research for tonight. i will leave these ugly bastards alone until tomorrow...

I wanted to try my hand at the fairly classic koi tattoo but with a personal twist. This one depicts a coelacanth which are lobe-finned fish known as "living fossils". They're relatives of our own fish ancestors prior to our lineage leaving the water.
