The first Silurian trilobite with three-dimensionally preserved soft parts reveals novel appendage morphology
<p>The first Silurian trilobite known with soft parts preserved, a <i>Dalmanites</i> species, is described from the Herefordshire Lagerstätte. Biramous appendages and much of the alimentary system are evident. High-fidelity three-dimensional preservation reveals a novel, double arrangement of the exopod filaments, interconnected by a presumed membranous sheet. This morphology explains a misinterpretation of the exopod as supporting spiral structures, originally reported nearly 150 years ago. The new exopod morphology is considered primarily respiratory in function and comparison with other trilobite limbs suggests that it may be unique to Phacopida.</p>

The Montane Hill Rat is the largest member of the B. fratrorum species group, with broad head, long rostrum, and robust body. Pelage is moderately long, soft, and lustrous, with shortish blackish guard hairs mixed throughout. Dorsum is brownish gray, speckled with buff that is a mix of dark gray underfur and overhairs with brown tips and buffy bands, being dark gray for the most part. Sides are paler grayish brown and fade into ventral pelage. Sides of muzzle are white. Venter is grayish white or dark grayish white, although some are grayish buff, with gray hairs and unpigmented tips or unpigmented altogether, respectively. Juveniles are duller and darker, with more grayish white underparts. Feet are long and slender, with white digits. Ears are large, covered in short unpigmented hair, rubbery, and gray and brown hues. Tail is 88-102% of head-body length and mainly bicolored, brownish gray to blackish gray dorsally and glossy white ventrally, with white tip most of the time. Scrotum is gray. Skull is large, with long and wide rostrum and narrow zygomatic plate. Fleas (e.g. Sigmactenus, Stivalius, Musserella, and Dasypsyllus), ticks (Rhipicephalus) pseudoscorpions (Magachernes and Chiridiochernes), and nematodes (Bunomystrongylus and Sibulura) have been recorded from the Montane Hill Rat.
