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: 2,4cm
REF.: #S535
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:
-对称的静脉沟
- Digit claw 底部为平整
- 末端的弯曲处是翼龙爪的特征：尖端在腹边有一薄薄的法兰或脊，在尖端处。它可被视为在峭壁上栖息时的最佳抓握适应。该法兰有助于勾住峭壁。
Observations about this specimen:
不寻常的顶端稀有标本，几乎几乎完整。我们将此爪归入 Ornithocheiridae 家族，因为仅有一只爪难以做出精确的分类。然而，它一定属于该科的始新世喀斯特尼亚鲁尼翼龙家族中的某一成员，该家族已在尼日尔的早白垩纪被描述。未修复或粘接。
