Grimaldi man was given to two Upper Palaeolithic human skeletons discovered in Italy in 1901. The remains are now recognised as belonging to two individuals. They are dated between 26,000 and 22,000 years ago (i.e., c. 24000–20000 BC) and classified as part of the late Aurignacian to early Gravettian Early European modern human population.

Several Stone Age finds of extreme age were discovered in caves and rock shelters around the “Balzi Rossi” (the Red Cliff) near Ventimiglia in Italy in the late 19th century. One of the more dramatic scenes featured two children wearing snail-shell belts and stone tools and several Venus figurines in the “Grotte des Fanciulli” (Cave of the Children). The archaeological exploration of the seven most important caves was funded by Albert I, Prince of Monaco, around the turn of the twentieth century. In honour of the House of Grimaldi, these were dubbed “Caves of Grimaldi.” The discovery is on display at Monaco’s Musée d’anthropologie préhistorique.

Several discoveries were made in the caves. The remains of one of the caves, the “Barma Grande,” were recently radiocarbon dated to 25,000 years old, putting them in the Upper Palaeolithic.

Time

Although dating techniques were limited, the Grimaldi people were thought to be from the late Palaeolithic period. The layering can be used to determine the true age. 

• The lower levels below the Grimaldi man skeletons had more tropical fauna, including rhinoceros, hippopotamus, and elephants, known from the Mousterian Pluvial, a wet period between 50,000 and 30,000 years ago.
• According to the most recent radiocarbon time scale calibration, the Aurignacian is 47,000 to 41,000 years old. The Grimaldi skeletons are found in the lowest Aurignacian layer, implying their true age is earlier.
• After discovering the first Cro-Magnon in 1868, it was assumed that modern man had emerged in Europe. 
• The Grimaldi finds were interpreted as ancestors of the Negroid race, just as the Chancelade skull suggested a Mongoloid ancestor. 

Physical characteristics of Grimaldi Man

The Grimaldi skeletons were unlike anything else discovered in Europe up to that point. The Grimaldi skeletons were slender and graceful, even more than the Cro-Magnon Man. Also, neither of the two skeletons of the Grimaldi Man were taller than 160 cm. The two skulls of Grimaldi man had rather tall braincases. The faces lacked the rectangular orbital, and broad complexion found in Cro-Magnons and had wide nasal openings. 

The discoverers concluded that the Grimaldi man was of the “negroid” type based on these characteristics.

Other physical characteristics of Grimaldi Man are as follows:

• Hyper Dolichocephalic people have long, narrow, and high skulls.
• Females have a cranial index of 68.5, while males have a cranial index of 69.2.
• The height of the head is approximately 11.5 cm.
• The female skull had a cranial capacity of 1265 C.C., while the male had 1455 C.C.
• Skulls represent an elliptical contour.
• The parietal bones’ regions have been flattened.
• Mastoid processes are insignificant.
• The face is broad but not disproportionately.
• The cheekbones are extremely narrow.
• The supraorbital ridges are underdeveloped.
• The forehead is well-developed, with a slight forward bulge.
• Orbits are sub-rectangular and large.
• The nose is large and broad (platyrrhine).
• The nasal root is depressed, and the nasal bridge is low.
• The nasal aperture’s lower border is not sharp.
• The canine fossae are quite extensive.
• The alveolar prognathism is quite noticeable.
• The palate is long, narrow, and deep.
• The alveolar border is in the shape of a U.
• The jaw is powerful.
• Raimi is ascending at a low level.
• The chin is underdeveloped.
• The lower jaw juts out in front of you.
• The teeth are quite large.
• The upper molars have four well-developed cusps, while the lower molars have five.
• The female is 5 feet 3 inches tall, while the boy is 5 feet 1 1/2 inches tall.
• In comparison to the upper limb, the lower limb is longer.
• In comparison to the arm and thigh, the forearm and leg are extremely long.

Phylogenetic Position

Not all early twentieth-century archaeologists agreed with Grimaldi’s assessment of African ancestors. While the Grimaldi man had “negroid” features, he also had European ones, according to Sir Arthur Keith. He concluded that the Grimaldi man was most likely an “intermediate race.” He speculated that the Grimaldi man may have crossed a land bridge from Africa to reach Europe. In the late Palaeolithic, both the Strait of Gibraltar and a route from Algeria via Sicily were fordable. Others have speculated that the Grimaldi were related to Bushmen.

Conclusion

In the scientific community, discovering more than 45,000-year-old human remains is always a cause for celebration. These discoveries are rare and valuable because each new sample or technique can reveal new threads in our understanding of Homosapien evolution. As a result, all human bones, both old and new, must be measured, cast, and sampled regularly. The positive (plaster, plastic, bronze, etc.) is cast, and the negative (usually a type of rubber) is created by brushing or pouring a material over the original. Bone or soft tissue can be used to make the cast.
