This species is dated to approximately 100–113 million years ago (Cretaceous) and is known from the Allaru Formation at Currane Station, Ilfracombe, Central West Queensland, as well as Bathurst Island in the Tiwi Islands of the Northern Territory. The species represents a nektonic ammonite that inhabited the warm shallow waters of the Eromanga Sea system.\u003c\/p\u003e\n\u003cp data-start=\"484\" data-end=\"930\"\u003eOriginally described in 1872 by Robert Etheridge as \u003cem data-start=\"536\" data-end=\"557\"\u003eAmmonites daintreei\u003c\/em\u003e, the species was based on fossil shell material discovered near Hughenden, Queensland. Etheridge named the species in honour of geologist and photographer Richard Daintree, whose name is also associated with the Daintree River and Daintree Rainforest of northern Queensland. The genus name \u003cem data-start=\"848\" data-end=\"863\"\u003eBeudanticeras\u003c\/em\u003e is thought to reference French geologist François Sulpice Beudant.\u003c\/p\u003e\n\u003cp data-start=\"932\" data-end=\"1684\"\u003eThe taxonomic history of \u003cem data-start=\"957\" data-end=\"982\"\u003eBeudanticeras daintreei\u003c\/em\u003e has changed several times since its original description. In 1892 Robert Etheridge Jr reassigned the species to the ammonite genus \u003cem data-start=\"1115\" data-end=\"1127\"\u003eHaploceras\u003c\/em\u003e. In 1921 Guido Bonarelli and Juan José Nágera transferred the species into the genus \u003cem data-start=\"1214\" data-end=\"1229\"\u003eBeudanticeras\u003c\/em\u003e, where it remains today. Dr Frederick W Whitehouse later established the separate genus \u003cem data-start=\"1319\" data-end=\"1332\"\u003eBoliteceras\u003c\/em\u003e in 1928, arguing that the fossils possessed distinctive features that separated them from other \u003cem data-start=\"1429\" data-end=\"1444\"\u003eBeudanticeras\u003c\/em\u003e species. However, later research by Dr Alberto C Riccardi and Francisco A Medina in 2002 concluded that these differences were insufficient to justify a separate genus and \u003cem data-start=\"1620\" data-end=\"1633\"\u003eBoliteceras\u003c\/em\u003e was subsequently synonymised with \u003cem data-start=\"1668\" data-end=\"1683\"\u003eBeudanticeras\u003c\/em\u003e.\u003c\/p\u003e\n\u003cp data-start=\"1686\" data-end=\"2052\"\u003e\u003cem data-start=\"1686\" data-end=\"1711\"\u003eBeudanticeras daintreei\u003c\/em\u003e belonged to the Desmoceratidae, a family of ammonites that first appeared during the Early Cretaceous and persisted until the Cretaceous–Palaeogene Extinction Event approximately 66 million years ago. Like other ammonites, the species possessed a chambered shell used to regulate buoyancy while swimming through ancient marine environments.\u003c\/p\u003e\n\u003cp data-start=\"2435\" data-end=\"2558\"\u003eEach specimen is carefully prepared and represents a unique fossil with natural variation in preservation and completeness.\u003c\/p\u003e\n\u003ch3 data-section-id=\"16zyfva\" data-start=\"2560\" data-end=\"2576\"\u003eKey features\u003c\/h3\u003e\n\u003cul data-start=\"2578\" data-end=\"2885\"\u003e\n\u003cli data-section-id=\"6sqqsz\" data-start=\"2578\" data-end=\"2607\"\u003eAuthentic fossil specimen\u003c\/li\u003e\n\u003cli data-section-id=\"11qnaq0\" data-start=\"2608\" data-end=\"2678\"\u003eTaxon: \u003cem data-start=\"2617\" data-end=\"2642\"\u003eBeudanticeras daintreei\u003c\/em\u003e (ammonite, Mollusca, Cephalopoda)\u003c\/li\u003e\n\u003cli data-section-id=\"vkafwf\" data-start=\"2679\" data-end=\"2722\"\u003eAge: 100–113 million years (Cretaceous)\u003c\/li\u003e\n\u003cli data-section-id=\"q3jucn\" data-start=\"2723\" data-end=\"2818\"\u003eOrigin: Allaru Formation, Eromanga Sea system, Queensland and Northern Territory, Australia\u003c\/li\u003e\n\u003cli data-section-id=\"1fzmh24\" data-start=\"2819\" data-end=\"2847\"\u003eMuseum-prepared specimen\u003c\/li\u003e\n\u003cli data-section-id=\"1qi4ddz\" data-start=\"2848\" data-end=\"2885\"\u003eNatural variation in preservation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3 data-section-id=\"yng56e\" data-start=\"2887\" data-end=\"2895\"\u003eNote\u003c\/h3\u003e\n\u003cp data-start=\"2897\" data-end=\"3128\"\u003eAs a natural fossil, variations in colour, texture and completeness are expected and add to the uniqueness of each specimen.
