賣家描述
Scientific name: cf Ornithocheirid Pterosaur ( cf Ornithocheirus simus, (Owen, 1861) - Pterosaur claw
Location: Gadoufaoua, Téneré Desert, Niger.
Geological Formation: Erlhaz Fm
Age: Lower Cretaceous, Aptian/Albian stage ( 113 million years)
Size: 32 mm • 1.26 in
REF.: #J410
DESCRIPTION:
Ornithocheirus simus, is only known from fragmentary jaw tips. It bore a distinctive convex "keeled" crest on its snout similar to its relatives. Ornithocheirus had relatively narrow jaw tips compared to the related Coloborhynchus and Tropeognathus, which had prominently-expanded rosettes of teeth, as well as a more developed "keeled" crest compared to Ornithocheirus. Another feature that made Ornithocheirus unique and unlike its relatives, was that its teeth of were mostly vertical, rather than set at an outward-pointing angle.
It was believed in the past that Ornithocheirus was one of the largest pterosaurs to have existed, with a wingspan possibly measuring 40 feet (12.2 m) wide.
Diagnostic characteristics of pterosaur claws:
-Symmetrical vein grooves
-The bottom of the digit claw is flat.
-The bend at the end of the tip is a specific trait of Pterosaur claws: The tip shows a thin flange or ridge of bone on the very tip on the ventral edge. It could be considered an adaptation for the best grip when perching on steep surfaces. That flange aids in hooking on cliffs.
Observations about this specimen:
Unsual top rare specimen, almost fully complete. We assign this claw to the family Ornithocheiridae, since a precise taxonomic classification is very difficult to arrive at with only one claw. However, it must belong to a pterosaur of this family, which has been described from the Early Cretaceous of Niger. Not restored or glued.
All of our fossils come with a Certificate of Authenticity. Every week, the issued Certificates of Authenticity are updated in our database verification system on our website. If you find that your certificate has not yet been updated, please contact us and we will update it immediately. Display box included.

賣家的故事
Jurassic Dreams 是全球最大的线上恐龙化石商店，作为获得真实化石标本最值得信赖的来源，独树一帜。我们是唯一由获认证的地质学家与古生物学专家共同拥有的领先线上化石商店。此外，我们还拥有来自宇宙各地的非凡真实陨石标本。
货架上有数十种不同标本……我们的客户一次次回头。因为简单来说，我们的终身保修无与伦比。
我名叫 Juan A. Poblador，在马德里大学和阿利坎特大学拥有扎实的古生物学与地质学学术背景。我从事恐龙化石挖掘工作超过十年，地点遍及欧洲与非洲等多地。撰写每一件标本的科学准确描述，是我工作中最耗时的任务之一。显然，识别假冒和修复过的化石对我来说是本能。因此，你可以肯定本网站的每一件化石都经过我仔细筛选与检验。
多年来，我为收藏家与化石爱好者提供服务，也向博物馆与机构供货。我将对重要标本的研究与学习，与展览和其他发现的销售结合起来，这有助于资助新的考察。
此外，我还拥有一支小型后勤支持团队，已由我亲自培训，确保能够妥善处理与包装化石，使其在24小时内发出并完好无损地送达。
最后但同样重要的是，我有幸与其他经验丰富的古生物学家建立了广泛的网络，在那里了解最罕见的物品、新发现以及前往偏远采石场的探险之旅……如果我遇到不知道的事，古生物学界的同行们会给予真正有用的帮助。
我喜欢把 Jurassic Dreams 打造成一个精心策划的线上博物馆级展览平台。我本人也是收藏家，乐于与其他收藏家分享知识。这就是为什么当你有疑问或购买时，我都会回复你的邮件，并为你提供个性化的化石选择体验。
Jurassic Dreams 自豪地成为应用古生物科学协会（AAPS）的成员并遵守其伦理准则。应用古生物科学协会的要求符合国家科学院关于化石收藏的建议，以及规范的商业实践与伦理。
此外，我们是国际陨石收藏家协会（IMCA）的认证成员 #5681，以及全球陨石协会（GMA） G0043 的认证成员。IMCA 与 GMA 是帮助陨石收藏家寻找真实陨石、拓展收藏知识、并协助他人了解陨石的最具声望的协会。
我们出售的每一件化石都附有免费提供的实体真实性证书。这是我们的终身保障。证书由古生物学专家 Juan A. Poblador 为每件化石单独撰写，包含准确的科学描述，证书的有效性可随时在线验证。此外，我们还提供 100% 的退款保证。
