Hedgehog-crab

Hedgehog Crab (Derilambrus angulifrons)

This spiky little crustacean belongs to the Parthenopidae family and is found in the deep waters of the Pacific Ocean.

Its spiny shell helps it blend in with rocky environments, offering protection from predators.

Despite its cute appearance, this crab is a skilled scavenger, feeding on small invertebrates and organic debris!

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.

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.

RARE: Megasqualus sp. British Eocene Shark Tooth, Woolwich Beds, Paleocene-Eocene, Beltinge, Kent, UK

This listing features a genuine Megasqualus sp. shark tooth fossil from the Woolwich Beds, dating back to the Paleocene-Eocene transition (~56 million years ago). This exceptionally preserved specimen was discovered in Beltinge, Kent, UK, a famous fossil locality known for producing high-quality early Paleogene marine fossils.

What is Megasqualus sp.?

Megasqualus is an extinct genus of squaliform sharks, closely related to modern dogfish sharks (Squalidae). These sharks were deep-sea predators, typically found in continental shelf and slope environments. Their teeth were adapted for seizing and tearing prey, likely consisting of smaller fish and cephalopods.

This species' teeth are distinctive due to their:

🔹 Slender, curved cusps—designed for efficient slicing and gripping of prey

🔹 Well-developed lateral cusplets—providing additional cutting edges for a strong bite

🔹 High enamel preservation—showcasing fine serrations and structural details

This particular specimen exhibits exceptional preservation, with a sharp, well-defined cusp, intact lateral cusplets, and finely detailed enamel, making it a rare and valuable addition to any fossil collection.

Fossil Details:

✅ Species: Megasqualus sp.

✅ Fossil Type: Shark Tooth

✅ Geological Formation: Woolwich Beds

✅ Geological Age: Paleocene-Eocene (~56 million years old)

✅ Location: Beltinge, Kent, UK

✅ Authenticity: 100% Genuine Fossil with a Certificate of Authenticity

Geological Significance:

The Woolwich Beds are a highly fossiliferous deposit from the Paleocene-Eocene boundary, a period of rapid climate change and marine ecosystem expansion following the end-Cretaceous mass extinction. These shallow marine and estuarine sediments preserve an extensive array of early Cenozoic marine life, including sharks, rays, mollusks, and invertebrates, offering valuable insights into early shark evolution.

Why This Fossil is Special:

🔹 Rare British Deep-Sea Shark Tooth – Megasqualus fossils are far less common than those of other Eocene shark species.

🔹 Exceptional Preservation – Displays sharp cusp, complete lateral cusplets, and high-quality enamel.

🔹 Museum-Grade Specimen – A highly collectible fossil, ideal for fossil collectors, researchers, and educational displays.

🔹 Guaranteed Authenticity – Comes with a Certificate of Authenticity for provenance verification.

📏 Scale Cube = 1cm – Please see photos for full sizing details.

📸 What You See Is What You Get – The specimen in the photos is the exact fossil you will receive.

This rare British Eocene shark tooth is a must-have for fossil collectors, educators, and paleontology enthusiasts, offering a unique glimpse into prehistoric deep-sea predators.

💎 Don’t miss this opportunity to own a scientifically significant and highly collectible fossil!

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

Adorabilis

Adorabilis (Opisthoteuthis adorabilis)

This irresistibly cute octopus belongs to the Opisthoteuthidae family and is found in the deep waters of the Pacific Ocean, off the coast of California.

With its round body, tiny fins, and big, puppy-like eyes, it looks like a real-life cartoon!

It’s a dumbo octopus relative, using its ear-like fins to gracefully flap through the water.
