dispel bones call out to her . On July 9 , 1965 , a confab scientist — the late Zofia Kielan - Jaworowska — took a stroll through the Mongolian Gobi Desert . Little did she know she was about to discover one of the weirdestnon - avian dinosaursknown to mankind .
Her 2013 Koran " In Pursuit of Early mammal " describes the scene :
Strewn across a desert hill , the giant fossilized arms were unlike anything paleontologists had ever seen before . Each of these three - fingered limbs measure about 8.2 feet ( 2.5 meters ) long . Impressed scientist named the animalDeinocheirus , which think " frightful hand . "
From 1963 through 1971 , Kielan - Jaworowska led several jointPolish - Mongolian Field Expeditionsthrough the Gobi . The find ofDeinocheirusin ' 65 was among their many highlights .
By the 1960s , Kielan - Jaworowska ’s name was well - known to scientist around the world . A leading paleontologist in her native Poland , she ’d follow up on her training at with child personal hazard duringWorld War II .
Research and Resistance
Born Zofia Kielan in Sokołów Podlaski , Poland , on April 25 , 1925 , she was 14 years old when Germanyinvadedher homeland during the fall of 1939 , setting off World War II . German troop would continue to occupy Poland until January 1945 .
want a instrumental workforce , the Nazis segregated learn establishment . Non - Germans living in Polish territory werebarredfrom obtain secondary or higher educations .
Yet there were those who defied the rescript . From her 2013 rule book :
start in 1943 , Kielan - Jaworowska call for covert classes through the University of Warsaw . She take to study fauna .
Earlier in the warfare , Kielan - Jaworowska had joined a resistance organization known as the " Grey Ranks . " They trail her to become a medic ; she ’d put those skill into practice during theWarsaw Uprisingof 1944 , a fail endeavor to kick out the German invader for safe .
A Rising Star
Kielan - Jaworowska creditedRoman Kozłowski(1889 - 1977 ) with provoke her interest in prehistoric lifetime .
A magisterial paleontologist , Kozłowski became one of Kielan - Jaworowska ’s professor in 1945 , after the University of Warsaw summarise normal operations .
Poland has an abundance of marineinvertebrate fogy . Ergo , most of Kielan - Jaworowska’searly researchfocused on trilobite , ancient beast relate to horseshoe crabs . While meditate these germ - same critter , she realize her Ph.D. in fossilology from the university in 1953 . It was during her graduate school age that she satisfy her next hubby , radiobiologist Zigniew Jaworowska . They were introduced during a 1950 mountain - climb slip and bind the knot eight years afterwards .
The year 1953 experience Kielan - Jaworowska join Kozłowski at theInstitute of Paleobiology , an organization run by the Polish Academy of Sciences . It was one of the many scientific enterprise that came of years during the Cold War .
The Politics of Fossil-Hunting
Back in the Roaring ' 20s , the American Museum of Natural History ( AMNH ) had organize multipleexpeditionsthrough theMongolian Gobi , a estate productive in fossils .
By all system of measurement , the campaigns were successful . AMNH researchers distinguish a whole slew of bewitching " Modern " dinosaurs ( such as the now - famousVelociraptorandProtoceratops ) from the Cretaceous Period , a stretchiness of deep time that lasted between 145 and 66 million year ago .
Then geopolitics intervene . Sandwiched between China and the U.S.S.R. , Mongolia emerge as a Soviet satellite . Few researchers from westerly area were set aside to visit its bountiful dig sites once the Cold War arrived .
But the situation was different for their counterparts behind the Iron Curtain , as Kielan - Jaworowska ground out .
fossilist and science communicator Donald Prothero explored Kielan - Jaworowska ’s life history in his book , " The Story of the Dinosaurs in 25 Discoveries : Amazing Fossils and the People Who find out Them . "
" She [ Kielan - Jaworowska ] take on vantage of the fact that , although Outer Mongolia was under Soviet domination and closed to westerly scientists , Polish scientists could get permission and funding , " Prothero says via email .
The Desert Beckons
Kielan - Jaworowska became the Institute of Paleobiology ’s director in 1961 , the year after Kozłowski go to sleep .
These two scientist were n’t done collaborating , however . Kozłowski hatched the estimate of organise a serial of collaborative Polish - Mongol palaeontology hostile expedition through the Gobi . At his suggestion , Kielan - Jaworowska write a detailed marriage proposal for three such journeying .
Both the Polish and Mongolian Academies of Science signed off on the projection . Kielan - Jaworowska was choose to be the enterprisingness ’s lead scientist and its main organizer .
Annalisa Berta is a paleontologist at San Diego State University who specializes in whale evolution . She also co - wrote the leger " Rebels , Scholars , Explorers : woman in Vertebrate Paleontology " with Susan Turner .
As Berta says via electronic mail , these Gobi Desert adventures made Kielan - Jaworowska " the first woman to lead a dinosaur excavation expedition . "
Gems of the Gobi
There were eight Polish - Mongolian expeditions in full ; Kielan - Jaworowskaled sevenof them .
BesidesDeinocheirus , Prothero says the participants unearthed " lots of Tyrannosaurus rex calledTarbosaurus . They found huge sauropod , and many different kinds of ' bone manoeuvre ' dinosaur , or pachycephalosaurs … a bunch of primitive horned dinosaurs ( Ceratopsia ) , and lots of ostrich dinosaur ( ornithomimids ) , including the famousGallimimusfrom Jurassic Park . The list goes on and on . " Her squad shipped back at least 20 tons of fossils to Poland in 1965 alone .
Two picky dinosaur stand out . In 1971 , an expedition member by the name of Andrzej Sulimski noticed a beautifulVelociraptorskeleton . As the radical dig out it up , a 2nd stern look . It bend out this bird of prey ’s fossilized consistence was intertwined with that of a plant - eatingProtoceratops .
Now internationally renowned , those " fighting dinosaurs " are housed at a museum in Ulaanbaatar , Mongolia , the nation ’s capital .
Even the well - planned journeys conduct unexpected risks . During the last of the Polish - Mongol expeditions , Kielan - Jaworowska ruptured her lefteardrumand went home to Poland on the advice of a local doctor . Three weeks later , she fly back to the Gobi .
Our Place in Nature
" As fossils from the expedition came pouring in , she navigated Cold War roadblocks to install ties with guide westerly scholars , notably those in Britain , France and the United States , " Berta says of Kielan - Jaworowska . " She built an telling skill internet from her hub in Warsaw that go throughout the man . "
Although Kielan - Jaworowska start out her life history as an invertebrate specialiser , her attention later shifted to prehistorical mammals .
" Before her work , most Cretaceous mammalian were only have a go at it from a few jaw and some teeth , " explain Prothero . " She found loads of complete skulls and skeletons of nearly all the major groups of mammalian that were around in the tardy Cretaceous . "
Beyond that , Kielan - Jaworowska changed the way scientists view some crucial ancestry . Deltatheridium — a rat - sized mammal that coexisted withVelociraptor — was primitively considered a placental mammalian . But new specimens Kielan - Jaworowska and her teams fetch to light betoken the tool was more kin to marsupial .
Kielan - Jaworowska died in Warsaw March 13 , 2015 , just a few workweek unsure of her 90th birthday . Glowing obit appeared in the journals " Nature " and " Acta Palaeontologica Polinica , " with both publishing calling her " a one and only role model . "
" She limit in motion a remarkable newfangled years of exploration and discovery , " Berta says . If there are any bud young dinosaur enthusiast in your living , you ’d do well to tell them her story .
