Taxonomy from Schweitzer et al. 2014. Quote (Schweitzer et al. 2014, p. 457): "Although the lobsters were interpreted as having relatively durable cuticle, the shrimp discussed herein are characterized by having very thin cuticle that is readily deformed and oriented in a variety of positions. As a result, the description and interpretation of the morphology of the shrimp is, of necessity, a composite of several specimens; however, fine detail of many parts of the skeletal anatomy is exquisite." Diagnosis from Schweitzer et al. 2014, p. 467: "Carapace longer than high; rostrum very long, 40 percent length of carapace, with one basal suprarostral spine and one subrostral spine at midlength; uropodal exopod with diaeresis; ventral lateral margins of telson with setal pits, appearing to extend entire length of telson; third maxilliped about as long as first and second pereiopods, with spine bases or setal pits along propodal and dactyl ventral margin; pereiopods 1– 3 chelate, third pereiopod longest, fourth and fifth longer than first and second, pereiopods without spines; pleopods apparently with multiarticulate flagellae." Identified by oilshale using Schweitzer et al. 2014. Characteristic is the extremely long rostrum, constituting 40 percent of the carapace length.

Originally named Sinosaurichthys by Wu et al., 2011, the genus was reranked as Saurichthys by A. Tintori (2013) Diagnosis from Wu et al. 2011, p. 595: "Medium−sized Sinosaurichthys (standard body length ranging from 270–470 mm) with unusually elongated median fins with relatively few segments of fin rays; less number of neural arches between opercle and caudal fin (approximately 157–172), less number of anterior ones with neural spines (130–146); and less number of mid−dorsal scales in front of dorsal fin (69–86) than in type species; 14–15 distinct haemal spines in caudal region; pectoral fin triangular shaped with length about 1/3 of mandible length (shared with S. minuta described below); posttemporal−supracleithrum from either side separated from each other by anterior mid−dorsal scales (shared with S. minuta described below); cleithrum plate (depth/length ratio ca. 1.2–1.25) much lower than in type species (approximately 1.8), but close to that in S. minuta (ap− proximately 1).

My friend found a clutch of fossil eggs from Qujing, Yunnan. The eggs are about 4cm in size and it is a large clutch. Any idea what species does the eggs belong to?

Taxonomy from Mindat.org. Diagnosis for the species by Tintori et al. 2010, p. 164: "Medium size, almost naked basal neopterygians with high fusiform body. Postero-ventral infraorbital much larger than the others; no suborbitals. Ventral surface of the parasphenoid and median surface of palatal bones totally covered by small teeth. Skull dermal bones with a ridged external surface, but with scarce ganoine covering. Vertebral column with no ossified or calcified centra. Autogeneous neural spines showing an enlarged leaf-like proximal end articulated to the corresponding enlarged distal area of paired neural arches. Short neural arches fused to the neural spines beginning from the end of the dorsal fin. Ossified ribs present, followed by haemal arches with a median spine at level of the insertion of the anal fin, Squamation constituted only by very small scales, arranged in a discontinuous row along the lateral line and in a single urodermal row on the dorsal body lobe of the hemiheterocercal tail. Last radial in both dorsal and anal fins supporting the last two or three lepidotricha. Median fins with very small scutes, several basal fulcra, very few and thin fringing fulcra. Size to at least 105 mm (S.L.); about 44 vertebral segments comprising the ural ones. All fins large and made by rather elongate lepidotrichia. Pectoral and pelvic fins made respectively by 13 and 8 lepidotrichia, dorsal and anal fin by 19 and 14 lepidotrichia. Caudal fin with 10 dorsal caudal fulcra, 3 dorsal unbranched, 17 segmented and branched, 3 ventral unbranched (at least two of them bearing few tiny fringing fulcra), 2-3 ventral caudal fulcra and 1-2 ventral scute. Dorsal body lobe with a single row of 12-13 urodermals, Cleithrum and postcleithrum ornamented by very low ridges with a dendritic pattern posteriorly directed."

Taxonomy from Hu et al. 2017. Revised diagnosis from Hu et al. 2017, p. 3: "Prosoma gently vaulted, semi-circular in outline, wider than long, lateral sides parallel, distally continuous into two genal angles. Cardiac lobe about 3/5 width of prosoma, tapering gradually forward. Ophthalmic ridges distinct, not meeting in front of the cardiac lobe. Eyes are low. Genal spines triangular, posteriorly directed, forming an acute angle with anterolateral margin of opisthosoma. Opisthosoma subtriangular, non-segmented, slightly wider than cardiac lobe, tapering backward gradually. Hinge relatively straight. Axial region in opisthosoma distinct, with a width 1/3 that of the opisthosoma. Six pairs of movable spines present on both sides of opisthosoma. Telson long and sword-like in outline, triangular in cross-section, with length equal to the body." References: Zhang, Q. Y., Hu, S. X., Zhou, C. Y., Lv, T. & Bai, J. K.
