Suchodus was named by Lydekker (1890). It was considered monophyletic by Bronzati et al. (2012).
It was synonymized subjectively with Metriorhynchus by Andrews (1913).
It was assigned to Geosaurinae by Young et al. (2010), Cau and Fanti (2011); to Thalattosuchia by Bronzati et al. (2012); and to Plesiosuchina by Young et al. (2024).

If no rank is listed, the taxon is considered an unranked clade in modern classifications. Ranks may be repeated or presented in the wrong order because authors working on different parts of the classification may disagree about how to rank taxa.
Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| M. T. Young et al. 2010 | Metriorhynchid thalattosuchian with less than 18 teeth per maxilla, and less than 18 teeth per dentary; variable ornamentation on the cranial bones, but lacking conspicuous ornamentation on the rostrum; the antorbital fossa is elongate, narrow, and oriented obliquely, and is enclosed by the lacrimal, maxilla, and jugal; the antorbital pseudofenestra is enclosed by the lacrimal, nasal, and maxilla; the internal nares opens out posteriorly into the buccal cavity, with the palatines creating an M-shape orientated anteriorly; the prefrontals are wider than the posteriorly orientated ‘V’ of the squamosal, created by the posterior margin of the supratemporal fossa; the prefrontals are greatly expanded over the orbits, with the lateral margins forming a 90° angle, giving it a distinct triangular shape; the postorbital process forming the supratemporal arch creates a 90° angle facing anterolaterally; the squamosal overlaps the parocciptial process extensively, projecting further caudally than the parocciptal process itself; the maxilla–palatine suture forms a broad U-shape, orientated anteriorly; the coronoid does not project rostrally as far as the tooth row; the mandibular symphysis depth is ~7–8% of the total mandible length; the squamosal contributes less than 50% to the supratemporal arch; the length of the cervical centrum is longer than its height; the atlas hypocentrum is longer in length than the odontoid process; the humerus is subequal in length to the scapula |
