解剖与古生物学细节
This lot features a highly detailed, scaled osteological replica of the distal portion of a Stegosaurus tail, scientifically recognized as the "thagomizer". -> 本批次包含一个高度详细的、缩尺的 Stegosaurus 尾端骨骼复制品，科学界公认的“thagomizer”（尾矛）。
This specific anatomical structure represents one of the most iconic defensive adaptations in dinosaur evolution. -> 这一特定解剖结构是恐龙进化中最具标志性的防御适应之一。
Caudal Morphology: The model accurately reproduces the terminal caudal vertebrae and the four hypertrophied dermal spikes (osteoderms). The angle and orientation of the spikes reflect the current paleontological consensus, illustrating how they protruded horizontally to inflict maximum structural damage against contemporary apex predators such as Allosaurus. -> 尾部形态：模型准确再现了末端尾椎和四个肥大皮甲刺（体表骨板）。刺的角度与方向符合当前古生物学共识，显示它们水平突出，以在当时对抗诸如异特龙等顶级掠食者时造成最大结构损伤。
Surface Osteology: The replica captures fine anatomical features, including the pronounced vascular grooves (blood vessel channels) along the spikes, which in life supported a keratinous sheath, making the weapons even longer and sharper than the fossilized bone alone. -> 表面解剖骨特征：复制品还原了刺上明显的血管沟（血管通道）等精细解剖特征，在生体中支撑着角质鞘，使这些武器比化石骨骼本身更长更锋利。

材料与技术实施
The replica is crafted from high-resolution polymer resin. The surface finish is entirely hand-painted, utilizing advanced acrylic wash techniques and dry-brushing to replicate the taphonomic permineralization typical of Jurassic fossils. -> 复制品采用高分辨率聚合物树脂制成。表面处理完全手工绘制，使用先进的丙烯酸洗涤和干刷技术，以再现侏罗纪化石常见的埋藏-矿化特征。

展示与安装
The specimen is securely mounted on a custom-designed ABS display base, providing a stable and elegant presentation. The contrasting matte finish of the base enhances the natural fossil tones of the replica, making it an ideal piece for scientific study, natural history collections, or private exhibitions. -> 标本固定在专门设计的 ABS 展示底座上，提供稳定而雅致的呈现。底座的对比哑光表面增强了复制品的自然化石色调，使其成为用于科学研究、自然历史收藏或私人展览的理想作品。
