BC-365 Bear Skull with Gunshot Wounds

Grizzly bears are among the largest and most formidable carnivores in the wild. This cast of a grizzly bear skull, marked by ballistic damage, tells a dramatic and compelling story. In a remote region of the Alaskan backcountry, two wildlife officials encountered this bear in a life-threatening situation. Although the officials survived the confrontation, the bear was fatally shot. The skull cast illustrates the trajectory of two .50 caliber bullets fired into the skull. One entered the cranium posterior of the left postorbital process on the frontal bone and the other on the left side of the snout above the infraorbital foramen. The bullets ricocheted within the cranium, causing extensive damage to the braincase before exiting through the lower portion of the cranium and fracturing the left ramus of the mandible. The full account of this extraordinary incident is documented in a video available on YouTube *link in bio*

Homo naledi Skull LES1
BH-061
*link in bio*

The hominin species Homo naledi, was first discovered in 2013 in the Dinaledi Chamber of the Rising Star Cave system in South Africa. Since then, fossils representing at least 18 additional individuals have been excavated, making the Rising Star Cave site the largest known collection of a single hominin species ever discovered in Africa. The fossils are dated to be approximately 236,000–335,000 years old.
What makes Homo naledi especially significant in the story of human evolution is its unusual mosaic of derived and ancestral anatomical features, as well as the fact that it lived in the same region and during the same time as early humans. H. naledi had a small brain, with a cranial capacity of just 465–610 cc—comparable to earlier australopithecines. Like members of the genus Homo, H. naledi possessed reduced postorbital constriction of the cranium, small teeth, and a gracile mandible. Postcranially, H. naledi retained more primitive characteristics, resembling the body plan of australopithecines.
The LES1 skull comes from the LES1 skeleton found in the Lesedi chamber within the Rising Star Cave system in South Africa. Based on partial cranial reconstruction, the endocranial volume was estimated to be 610cc.

In June 2026, a study of dental enamel proteins produced a surprising result: every excavated H. naledi tooth analyzed contained protein markers consistent with female biological s*x (Madupe et al. 2026). This unexpected finding deepens the mystery surrounding Homo naledi, raising new questions about the composition of the fossil assemblage, the species’ biology, and the circumstances that led to the accumulation of these remains in the Rising Star Cave system.

Fossil Whale Teeth, Basilosaurus cetoides, Set of 16
KO-530-SET

This archaeocete whale from the late Eocene is believed to be around 35 million years old. It is found in the Gulf Coast states of the United States, with a significant presence in Alabama, where it has been designated the official state fossil.

Basilosaurus, one of the first fully aquatic whales, had large multi-cusped teeth adapted for shearing fish and squid, with cheek teeth about 2 inches wide and tall. Unlike modern cetaceans, Basilosaurus possessed a variety of teeth, including canines and molars, which suggests it may have been capable of chewing its food. It is believed to have been one of the largest animals of the Paleogene period, reaching around 70 feet in length and weighing up to 15 tons! As a fierce apex predator, Basilosaurus hunted sharks, large fish, and the smaller dolphin-like relative, Dorudon.
Whales evolved from terrestrial mammals and are part of the large group of mammals that are even-toed ungulates called Artiodactyla. While modern whales lack external hind limbs, they have vestigial pelvis bones, a last remitment of their ancient terrestrial heritage.

🚨New Product Alert🚨

BC-370 Sloth Bear Skull

Sloth bears are found across South Asia, including India, Sri Lanka, and Nepal. They are recognized by their shaggy black coats, pale snouts, long claws, and flexible lips. Adults can grow up to 6ft long and weigh up to 300lbs. Sloth bears have the longest claws of any bear relative to body size, reaching up to 3in long. These claws are ideal for tearing apart termite mounds and rotting logs. A gap between their front teeth and powerful sucking lips helps them feed on termites and ants, which make up much of their diet alongside fruit and honey.

They inhabit lowland tropical forests, grasslands, and scrublands across South Asia. Although known for aggressive encounters with humans, attacks usually happen when the bears are startled or protecting cubs, often due to increasing human activity in their habitat.

Sloth bears are currently listed as Vulnerable on the IUCN Red List because of habitat loss, poaching, and human-wildlife conflict.

Hands!

Homologous structures are shared anatomical elements found in different organisms that share a common ancestor. Across many vertebrates (organisms with backbones), the elements that make up the hand or manus share the same bone plan because it was inherited from a common ancestor. Here are some of our favorites!

KO-211-MH Human Magnetic Hand
An innovative concept that adds a dynamic component to the study of hand and foot anatomy! Strategically built-in magnets help guide the assembly as students learn about the intricate features of the individual bones and their articulations. All but the medial/distal phalanges are completely separable in our unique Magnetic Hand.

KO-114W Short-faced Bear Paw
The short-faced bear (Arctodus simus) had long limbs and would have dwarfed both the European cave bear and the modern Kodiak bear. The Andean bear is its closest surviving relative. The short-faced bears found in Alaska (such as this one) are typically more robust than those found farther south. Arctodus simus became extinct about 10-12 thousand years ago.

SC-027-24-A Komodo Dragon Hand
Komodo dragons, endemic to a few small islands in Indonesia, are the largest of the world’s lizards. Komodos, like most lizards, have a pentadactyl limb arrangement.

KO-233 Bottlenose Dolphin Pectoral Fin
While the dolphin’s pectoral flipper, which is used for steering as well as touching other dolphins, may have different functions than the human arm, its skeletal make-up is basically the same. However, the bones that are comparable to the humerus, ulna and radius of the human are foreshortened in the dolphin. The dolphin’s flipper bones are firmly held together by connective tissue and cartilage.

Teeth!

7 1/8 Inch Megalodon Shark Tooth KO-008

The Megalodon shark became extinct at the end of the Pliocene Era, 1.5 million years ago. Sharks will go through about 20 thousand teeth in its lifetime. This tooth is among the largest found and came from a 50 foot Megalodon that lived about 20 million years ago.

Great White Shark Tooth KO-223

The great white shark has 5 rows of 46 teeth for a total of 230. The jaw is approximately 35 inches across and 29 inches high. A great white shark can weigh as much as 7000 pounds.

Tyrannosaurus rex Tooth KO-039

Tyrannosaurus had a mouth full of large serrated teeth capable of tearing though the flesh of any large contemporary dinosaur.

Sabertooth Cat, Smilodon Saber KO-212

The sabertooth cat skull gives the impression that the sabers are so long, the cat could not get any food in its mouth. However, the jaw opens much wider than that of modern cats.

Human Skull, Porotic Hyperostosis and Cribra Orbitalia

BC-405

Porotic hyperostosis and cribra orbitalia are porous cranial lesions that are associated with metabolic or general nutritional stress. It is said to be caused by iron deficiency anemia, nutrient deficiencies, infectious disease, and/or poor sanitation. However, recent studies have suggested that hemolytic and megaloblastic anemias are the more likely cause of porotic hyperostosis. Porotic hyperostosis occurs as porous areas on the skull vault, while cribra orbitalia refers to porous areas within the orbits. This skull exhibits porotic hyperostosis involving posterior portion of the frontal bone, across the coronal suture into the left parietal bone. A small quarter-sized defect can be seen on the right parietal bone. Cribra orbitalia can be seen on the roof of the left eye orbit.

King Penguin Skull
BC-368

King penguins, the second-largest species of penguin, are visually striking birds with their vibrant orange and yellow markings and tuxedo-like plumage. One particularly interesting skeletal feature is their solid bones, contrasting with the hollow bones of flying birds. This dense bone structure helps them dive to depths over 300 meters by reducing buoyancy. Additionally, their flipper-like wings, anchored by a flat sternum and supported by a shortened humerus, are powerful tools for “flying” underwater, making them expert deep-sea foragers, chasing prey with remarkable agility and speed.
