本文研究了三个属的鳞片（Aspidorhynchus，Belonostomus，and Adultifer），以揭示一些有助于理解该科在新鸟纲中系统位置的特征。所研究的9个种的鳞片均为鳞骨型，鳞片上覆盖一层硬鳞，基板由具有威廉姆森小管的板层骨构成。有些种类的Aspidorhynchus没有鹅膏蛋白，而其他种类只有一层薄薄的鹅膏蛋白。在盾吻类的鳞片中发现的特征都不能被认为是一个能够将该分支置于硬骨鱼类中的家族性突触形态，这种情况并不意味着将这个家族排除在这个主要群体之外。
The scales of the three genera of aspidorhynchids (Aspidorhynchus, Belonostomus, and Vinctifer) are studied to bring out some characters useful to understand the systematic position of aspidorhinchids within the neopterygians. The scales of the nine species studied are of lepidosteoid type with a ganoine layer overlaying a basal plate made of lamellar bone with canalicules of Williamson. Some species of Aspidorhynchus are devoid of ganoin, whereas others show only a thin ganoine layer. None of the characters found in the scales of aspidorhynchids can be considered as a familial synapomorphy able to place the clade within the teleosts, a situation that does not imply the exclusion of this family from this major group.
