Some 100,000 years ago , an drawn-out family of 36Neanderthalswalked along a beach , with the kids leap and frolicking in the sand , scientist report after analyze the beachgoers ' fossilized footprint in what is now southern Spain .
" We have find some expanse where several small footprints appear grouped in a chaotic arrangement , " say Eduardo Mayoral , a paleontologist at the University of Huelva and lead author of the bailiwick , which was published online March 11 in the journalScientific Reports .
The fossilized footprints discovered on a beach in southern Spain are thought to be more than 100,000 years old and may be the earliest Neanderthal footprints found in Europe.
The step " could designate an area of passage of very young individuals , as if they were playing or loitering on the shore of the nearby waterlogged sphere , " Mayoral differentiate Live Science in an email .

In June 2020 , two biologists discovered the tracks on Matalascañas beach , in Doñana National Park , after a menses of intense storm and in high spirits lunar time period .
The footprints were found on on Matalascañas beach in Andalusia after storms and high tides exposed the surface where they were made (marked here as HTS), now just above the waterline of the coast.(Image credit: Mayoral et al./Scientific Reports)
The biologists first saw fossilized animal tracks ; some of the footprint were made long ago by large fauna , like deer or wild boars , Mayoral said .
Only later , after Mayoral ’s squad analyse the print , did anyone realize that some were Neanderthal footprint , he said . " Nobody recognized the cosmos of the hominid footmark at that metre , which were only expose by my squad two month later , when we start to study the whole surface in particular . "
Ancient footprints
Mayoral and his colleagues identified 87 loutish footprints in the aqueous rock on the beach at Matalascañas . ( The researchers determined those print were made by 36 individual . )
The exposed surface go out to the Upper Pleistocene period , roughly 106,000 geezerhood ago , when ancient stone pecker chance on nearby show the region was inhabit by Neanderthals ( Homo neanderthalensis ) . These hunter - gatherers lived in Europe and the Middle East between 400,000 and 40,000 years ago , while early modern humans(Homo sapiens)arrived there about 80,000 years ago . The research worker consider the track could be the oldest loutish footprints ever found in Europe .
At the time the footprint were made , the now - bring out surface appears to have been along the shore of a tearing hole slightly inland from the seacoast , which was farther south back then than it is today , Mayoral said .
The scientific team estimates the fossilized footprints were made by a group of 36 Neanderthals that included 11 children – some of whom appear to have been playing in sand that became sedimentary rock.(Image credit: Mayoral et al./Scientific Reports)
" Probably the H2O would not have been refreshed but fairly brackish , since we have found grounds of sea salt crystal ( halite ) on the surface where the footprint are found , " he wrote in the email .

The squad photographed the website extensively with an aerial radio-controlled aircraft and digitally scanned each of the fossilize human footprints in three dimensions .
The Neanderthal group that left the footprints may have been hunting, fishing, or gathering shellfish in a brackish watering hole near the coast about 106,000 years ago.(Image credit: Mayoral et al./Scientific Reports)
The sizes and statistical distribution of the footprints propose they were made by a group of 36 Neanderthal mortal who were probably link , including 11 children and 25 adults — five females , 14 males and six individuals of unresolved sex .
" It can be set up by correlativity with other European sites that there is a direct human relationship between the size of a footmark and the age of the somebody who produced it , " Mayoral said .
Most of the beach - walking adult would have stood between 4 and 5 foot ( 1.3 to 1.5 meter ) marvellous , but four prints seem to have been made by an individual who was over 6 foot ( 1.8 m ) marvellous . That ’s taller than the expected stature of Neanderthals , so the photographic print may have been made by a shorter soul with a heavy pace , the researchers wrote .
Scientists say the footprints are the first direct evidence that the region was inhabited by Neanderthals, who lived in parts of Europe for about 300,000 years before the first early modern humans arrived.(Image credit: Mayoral et al./Scientific Reports)
Playing in the sand
Of particular interest are the two lowly footprint , approximately 6 inches ( 14 centimeters ) long , that are thought to have been made by a baby about 6 geezerhood old . They are among several footprints grouped chaotically in some orbit , mayhap because the Neanderthal children were play in the Amandine Aurore Lucie Dupin on the shore of the lachrymation hole , Mayoral said .
Analysis of the trail show that most of the footprints are locate on the edge of the flooded area , but the individuals who made the prints did not move entirely into the water , the researcher wrote .
" This could involve a search scheme , stalking animals in the water [ such as ] waterbirds and wader or small carnivores , " they wrote .

The rails might also have been made by people fishing in the water hole or look for for mollusk ; grounds of similar search - and - gather behavior by Neanderthals has been reported at other ancient situation .
Stone tools attributed to Neanderthals have turned up at nearby sites , but in those cases , there was no direct grounds — such as Neanderthal bones or teeth — to corroborate their presence , Mayoral said .
That made the fossilised footprints particularly important , the researchers wrote : " The biological and ethological info of the ancient hominin groups when there are no os stay , is provided by the study of their fossil footmark , which show us certain ' wintry ' moments of their existence . "
The footprints were " authentic proof of these hominids ' macrocosm in the south of the Iberian Peninsula and , specifically , in this domain of the Andalusian slide , " Mayoral said .
