卖家的描述
Scientific name: Tyrannosaur Dinosaur - Nanotyrannus sp - Theropod Dinosaur Tooth
Location: Fallon Co., Montana (Private Land), USA
Geological Formation: Hell Creek Fm
Age: Late Cretaceous, Maastrichtian stage (~68-66 Million Years)
Size: 2cm
REF.: #J116
DESCRIPTION:
Authentic Nanotyrannus sp. tooth from the famous Late Cretaceous deposits of Montana, USA.
它在切割边缘（carina）处锯齿保存异常完好。只有尖端区域略微受损。
100% natural, with absolutely no restoration or repairs.
Nanotyrannus lancensis is a small, fast, agile tyrannosaur from the Late Cretaceous Hell Creek Formation (originally part of the Lance Formation), known for being small and distinctly different from T. rex, with recent studies confirming it's a separate species, not a juvenile T. rex, based on unique features like more teeth, larger hands, and distinct bone structures. Meaning "dwarf tyrant," it was a capable predator of smaller prey, coexisting with T. rex.
Key Facts
Name Meaning: "Dwarf tyrant" from Greek nanos (dwarf) and tyrannos (tyrant).
Species Name: lancensis refers to the Lance Formation where its skull was found.
Size: Around 15-18 feet long, much smaller and lighter than an adult T. rex.
Habitat: Hell Creek Formation (Late Cretaceous), same time and place as T. rex.
Lifestyle: Fast, agile pursuit predator, likely hunting smaller dinosaurs like pachycephalosaurs.
Controversy: Long debated as either a distinct species or juvenile T. rex, but recent evidence strongly supports it as its own genus.
Distinguishing Features: Narrower skull, more teeth, larger hands, and different bone structures than T. rex.
The Debate & Resolution
Juvenile T. rex Theory: Many scientists thought smaller tyrannosaur fossils from Hell Creek were young T. rex because no large Nanotyrannus fossils existed, and T. rex juveniles were rare.
Separate Species Theory: Researchers found that Nanotyrannus fossils showed adult-like traits (fused bones) and unique features that T. rex never developed, making it biologically impossible to grow into a T. rex.
Current Consensus: Nanotyrannus is a separate, distinct genus of small tyrannosaur, coexisting with T. rex as a unique, agile predator.

卖家故事
Jurassic Dreams 是全球最大的在线恐龙化石商店，作为获取真实化石标本的最有信誉来源，独树一帜。我们是唯一一家由经过认证的地质学家和古生物学家拥有的领先在线化石商店。此外，我们还拥有来自宇宙各处的非凡真实陨石标本。
库存中有几十种不同标本……我们的客户一次又一次地回头来购买。因为，简单来说，我们的终身保修无与伦比。
我叫 Juan A. Poblador，在 Paleontology and Geology 领域具备扎实的学术背景，来自 University of Madrid 和 University of Alicante。我在欧洲和非洲等地的多个地点参与过化石挖掘项目超过十年。撰写每个标本的科学准确描述是我的工作之一，耗时较多。显而易见，识别假冒与修复过的化石对我来说是本能。因此，你可以放心，本网站的每一块化石都经过我仔细筛选与检查。
多年來，我为收藏家和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研究成果，与展览及其他发现的销售结合起来，这有助于资助新的考察。
此外，我还有一个小型后勤支持团队。我亲自培训他们，确保妥善处理和打包化石，使其能够在24小时内发出，安全无损地送达您的门口。
最后但同样重要的是，我很幸运拥有一个庞大的经验丰富的古生物学家网络，我们会讨论最罕见的物品、新发现和前往偏远采石场的勘探之行……如果我不知道某些事情，古生物学界真的会提供帮助。
我喜欢把 Jurassic Dreams 打造成一个经过精心策展的博物馆级藏品在线展览。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，当你有任何疑问或购买时，我都会回复你的一封邮件，你将获得个性化的化石选择体验。
Jurassic Dreams 自豪地成为 Applied Paleontological Sciences 协会（AAPS）成员，并遵守其道德准则。Applied Paleontological Sciences 协会遵循 National Academy of Sciences 关于古生物学收藏与标准商业实践与伦理的建议。
此外，我们还是 International Meteorite Collectors Association (IMCA) 的认证成员 #5681，以及 GMA (Global Meteorite Association) 的认证成员 G0043。IMCA 与 GMA 是帮助行星铁陨石收藏家寻找真实陨石、丰富收藏知识、并促进学习的最负盛名的协会。
每售出一块化石，我们都会免费提供一份实体真实性证书。这是我们的终身保修。证书由 Juan A. Poblador，一位资深古生物学家，专门为每块化石单独准备，包含准确的科学描述，证书的有效性可随时在线验证。此外，还提供 100% 退款保证。
