Originally described by Johann Andreas Wagner in 1861, this taxon became one of the classic species of European palaeontology and was long celebrated as one of the smallest known non-avian dinosaurs. Its generic name means “elegant jaw” or “refined jaw”, while the specific epithet \u003cem data-start=\"571\" data-end=\"581\"\u003elongipes\u003c\/em\u003e refers to its long hind limbs.\u003cspan aria-hidden=\"true\" class=\"PDq2pG_selectionAnchor\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp data-start=\"614\" data-end=\"1328\"\u003eGeologically, \u003cem data-start=\"628\" data-end=\"652\"\u003eCompsognathus longipes\u003c\/em\u003e lived during the Late Jurassic, particularly from the latest Kimmeridgian to the Tithonian, approximately 150 million years ago. The environments of Solnhofen and Canjuers consisted of coastal lagoon systems, islands, shallow carbonate settings and finely sedimented basins, where exceptional preservation conditions allowed reptiles, fishes, invertebrates, pterosaurs, early birds such as \u003cem data-start=\"1043\" data-end=\"1058\"\u003eArchaeopteryx\u003c\/em\u003e, and small theropod dinosaurs to fossilise in remarkable detail. The French specimen from Canjuers was revised in 2006 and regarded as a subjective synonym of \u003cem data-start=\"1218\" data-end=\"1242\"\u003eCompsognathus longipes\u003c\/em\u003e, expanding anatomical knowledge of the species beyond the original Bavarian specimen.\u003c\/p\u003e\n\u003cp data-start=\"1330\" data-end=\"2056\"\u003eFrom a morphometric perspective, \u003cem data-start=\"1363\" data-end=\"1387\"\u003eCompsognathus longipes\u003c\/em\u003e was a small and gracile theropod. The German specimen, traditionally interpreted as the smaller individual, measures approximately 85–90 centimetres in total length, while the French specimen reaches around 1.20–1.25 metres. Hip height would have been relatively low, approximately 25–35 centimetres depending on the individual and reconstructed posture, and body mass was probably only a few kilograms. These proportions made it a lightweight, fast and very slender animal, quite unlike the large predatory theropods of the Jurassic. The palaeontological literature generally places compsognathids among small basal coelurosaurs, typically around one metre in length.\u003c\/p\u003e\n\u003cp data-start=\"2058\" data-end=\"2740\"\u003eAnatomically, \u003cem data-start=\"2072\" data-end=\"2096\"\u003eCompsognathus longipes\u003c\/em\u003e possessed a narrow, elongated skull, delicate jaws, small sharp teeth, a flexible neck, a lightly built torso, a long tail and proportionally well-developed hind limbs. Its long legs suggest active and agile locomotion, well suited to moving rapidly through insular or coastal environments. The forelimbs were shorter than the hind limbs but remained functional, with hands capable of assisting in the capture or restraint of small prey. Detailed studies of the hand morphology of \u003cem data-start=\"2578\" data-end=\"2593\"\u003eCompsognathus\u003c\/em\u003e have also contributed to revisions of the diagnosis of Compsognathidae and to understanding the early evolution of the hand in basal coelurosaurs.\u003c\/p\u003e\n\u003cp data-start=\"2742\" data-end=\"3396\"\u003eThe diet of \u003cem data-start=\"2754\" data-end=\"2778\"\u003eCompsognathus longipes\u003c\/em\u003e is among the best documented for a small Jurassic theropod thanks to preserved abdominal contents. The German specimen contains the remains of a small lizard in the abdominal region, traditionally identified as \u003cem data-start=\"2990\" data-end=\"3004\"\u003eBavarisaurus\u003c\/em\u003e, while the French specimen preserves partially digested remains of small reptiles. This evidence indicates that \u003cem data-start=\"3117\" data-end=\"3132\"\u003eCompsognathus\u003c\/em\u003e was an active predator of small vertebrates, probably capable of capturing lizards, juvenile reptiles, large insects and other small animals. Its lightweight build, fine dentition and long hind limbs are consistent with a fast and opportunistic hunting lifestyle.\u003c\/p\u003e\n\u003cp data-start=\"3398\" data-end=\"4003\"\u003eAlthough no direct feather impressions are known in association with \u003cem data-start=\"3467\" data-end=\"3491\"\u003eCompsognathus longipes\u003c\/em\u003e, its position within Coelurosauria and the presence of filamentous integument in related compsognathids such as \u003cem data-start=\"3604\" data-end=\"3621\"\u003eSinosauropteryx\u003c\/em\u003e make some form of simple filamentous covering, at least partial, a plausible reconstruction. This interpretation should be applied cautiously, clearly distinguishing between direct evidence and comparative inference, but it is consistent with the modern view of many small coelurosaurian theropods as having a more bird-like appearance than traditionally reptilian reconstructions.\u003c\/p\u003e\n\u003cp data-start=\"4005\" data-end=\"4053\"\u003e\u003cstrong data-start=\"4005\" data-end=\"4053\"\u003eApproximate Compsognathus Replica Dimensions\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp data-start=\"4055\" data-end=\"4166\"\u003e\u003cstrong data-start=\"4055\" data-end=\"4086\"\u003e1:10 Scale — Complete Model\u003c\/strong\u003e\u003cbr data-start=\"4086\" data-end=\"4089\"\u003eLength: 98 mm\u003cbr data-start=\"4102\" data-end=\"4105\"\u003eHeight: 50 mm\u003cbr data-start=\"4118\" data-end=\"4121\"\u003eWidth: 17 mm\u003cbr data-start=\"4133\" data-end=\"4136\"\u003eSnout-to-tail length: 120 mm\u003c\/p\u003e\n\u003cp data-start=\"4168\" data-end=\"4277\" data-is-last-node=\"\" data-is-only-node=\"\"\u003e\u003cstrong data-start=\"4168\" data-end=\"4198\"\u003e1:6 Scale — Complete Model\u003c\/strong\u003e\u003cbr data-start=\"4198\" data-end=\"4201\"\u003eLength: 163 mm\u003cbr data-start=\"4215\" data-end=\"4218\"\u003eHeight: 83 mm\u003cbr data-start=\"4231\" data-end=\"4234\"\u003eWidth: 28 mm\u003cbr data-start=\"4246\" data-end=\"4249\"\u003eSnout-to-tail length: 200 mm\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/section\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"Miniature Museum","offers":[{"title":"1:10 \/ Sin imprimar","offer_id":62035864748300,"sku":"DC-1534-135-SINI","price":29.9,"currency_code":"EUR","in_stock":true},{"title":"1:10 \/ Imprimado","offer_id":62035864781068,"sku":"DC-1534-135-IMPRI","price":34.9,"currency_code":"EUR","in_stock":true},{"title":"1:10 \/ Pintado a mano","offer_id":62035864813836,"sku":"DC-1534-135-PINTA","price":94.6,"currency_code":"EUR","in_stock":true},{"title":"1:6 \/ Sin imprimar","offer_id":62035864846604,"sku":"DC-1534-120-SINI","price":40.4,"currency_code":"EUR","in_stock":true},{"title":"1:6 \/ Imprimado","offer_id":62035864879372,"sku":"DC-1534-120-IMPRI","price":47.4,"currency_code":"EUR","in_stock":true},{"title":"1:6 \/ Pintado a mano","offer_id":62035864912140,"sku":"DC-1534-120-PINTA","price":166.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0672\/1106\/7660\/files\/Compsognathuslongipes_7.png?v=1786883940","url":"https:\/\/dinosauriacreatures.com\/en\/products\/compsognathus-longipes-4","provider":"Dinosauria Creatures","version":"1.0","type":"link"}
