Taxonomy
Mulinia pabloensis was named by Packard (1916). Its type specimen is UCMP 11442, a shell, and it is a 3D body fossil.
It was recombined as Pseudocardium pabloensis by Hall (1958) and Moore (2003).

Diagnosis

|---|---|---|
| Packard in Clark 1915 | Shell rather ventricose, nearly equilateral, umbones usually posterior to the middle of the shell; anterior dorsal edge nearly straight, excavated in front of the beaks; anterior extremity rounded to subtruncate; posterior dorsal edge slightly convex, extremity strongly truncated; some specimens show a posterior umbonal ridge, which is imperfectly seen in the type; base broadly arcuate. Surface roughened by numerous irregular lines of growth. Pallial sinus shallow; other muscle scars deeply impressed. The hinge of the type lacks the posterior laminae and the posterior arm of the cardinal. Hinge plate rather heavy, chondophore relatively shallow, roofed; right cardinal with a small anterior arm which is closely appressed to the dorsal margin of the shell; anterior laminae long, strongly striated on their inner sides, the dorsal one being nearly as long as the ventral one, and arising as a long thin tooth, from the hinge plate to a height greater than that of the adjacent shell margin. In one specimen the ventral lamina is rather heavy and distinctly striated, not confluent with the anterior arm of the cardinal. The cotype shows the left valve with a rather small but prominent cardinal and large striated laterals, which are distant from the umbones, the anterior one not reaching to the cardinal arm. The dimensions of the type are: height, 43 mm., convexity, 18 mm. Those of the cotype are: length, 54 mm., height, 48 mm., convexity, 36 mm. |
