Laparon alticeps

Laparon alticeps is the second member of the spadefish family (Ephippidae) to be represented in the London Clay. From the specimens observed, this is a much smaller fish than Whitephippus but shares the central ridge on the top of the skull and the lateral-compression to the body.

Distinguishing Characteristics:

Raised profile at rear of skull (poor preservation on holotype) (1)
Distinct V-shape (2)
Course striations on the Hyomandibular (3)
Sclerotic ossicle present in eye orbit (4)
