FIGURE 5 in Review of the Indian Ocean spikefish genus Mephisto (Tetraodontiformes Triacanthodidae)
FIGURE 5. Mid-body scales of Mephisto. Anterior to left. A–C Mephisto fraserbrunneri, USNM 350153, 105.8 mm SL. A. Patch of scales. White arrows indicate tips of bifurcate spinules at base of central spinules; black arrows indicate tips of central spinules. B. Single scale showing five spinules, including a central spinule with a bifurcate spinule at its base and both branched and unbranched dorsal and ventral spinules. White arrows indicate tips of single or bifurcate spinules; black arrow indicates central spinule tip. C. Illustration of single scale from M. fraserbrunneri to show relative length of spinules when viewed obliquely and for comparison with images B and D. D. Illustration of a single scale of M. albomaculosus, NSMT-P 132271, 94.4 mm SL. Illustration from Matsuura et al. (2018), reprinted with permission from the Ichthyological Society of Japan. Note, scale has been reflected so image faces left. In large specimens of both M. fraserbrunneri and M. albomaculosus the central spinule has a bifurcate branch. Apparent differences in shape of scale plates in parts C and D is because the regions of overlap are not shown in part D.

Data from: Mosaicism in a new Eocene pufferfish highlights rapid morphological innovation near the origin of crown tetraodontiforms
Tetraodontiformes (pufferfishes and kin) is a taxonomically and structurally diverse, widely-distributed clade of acanthomorphs, whose members often serve as models for genomics and, increasingly, macroevolutionary studies. Morphologically disparate Palaeogene fossils suggest considerable early experimentation, but these flattened specimens often preserve limited information. We present a three-dimensionally preserved beaked tetraodontiform from the early Eocene (c. 53 Ma) London Clay Formation, UK. Approximately coeval with the oldest crown tetraodontiforms, †Ctenoplectus williamsi gen. et sp. nov. presents an unprecedented combination of characters, pairing a fused beak-like dentition with prominent dorsal-fin spines that insert atop transversely-expanded pterygiophores roofing the skull. Bayesian total-evidence tip-dating analysis indicates that †Ctenoplectus represents the sister lineage of Triodontidae and highlights considerable levels of homoplasy in early tetraodontiform evolution. According to our dataset, rates of morphological character evolution were elevated at the origin of crown Tetraodontiformes, especially within gymnodonts, but declined after the principal body plans were established. Such 'early burst' patterns are regarded as a hallmark of adaptive radiations, but are typically associated with diversification at smaller spatiotemporal scales. However, denser sampling of Neogene and Recent taxa is needed to confirm this pattern.
