Brachygnathosuchus

Brachygnathosuchus is an extinct genus of crocodilian. Fossils have been found from the Upper Purus River in western Brazil. As there were no lithified strata for the original specimen to be correlated with, the fossils cannot be dated with any certainty. However, partial remains of different organisms found in the vicinity of the specimen, such as a possible Megamys tooth and a humerus of a megalonychine ground sloth, suggest that they were of Pliocene age. The name Brachygnathosuchus refers to its characteristically broad, stout mandible, unusual among crocodilians. The holotype specimen was referred to Crocodilia on the basis of a partial right ramus of the lower jaw consisting of a portion of a very large dentary bone. The bone differs from those of other related fossil and modern crocodilians and was originally said to resemble that of a dinosaur. An eroded osteoderm also associated with the specimen provides further evidence for its classification as a crocodilian.

No picture of Brachygnathosuchus was found. Wikipedia, Wikidata and iDigBio were searched and had none. Smithsonian Open Access did not answer, so this is what the others held rather than everything there is. GBIF was asked, and what came back is not recorded: nothing, or a picture this site could not tie to Brachygnathosuchus, or no answer at all. This entry cannot say which.

Time the record covers

At most 4.4 million years on record.

The one occurrence read is dated to somewhere between 11.63 Mya and 7.246 Mya, which is a dating window rather than a span.

1 occurrence of Brachygnathosuchus on record, most of them in the Miocene. Bar height is expected occurrences, not a count: each fossil is spread across the span it is dated to, so a tall narrow bar means tight dating and a low wide one means loose.

When

1 occurrences

These are dates about fossils, not the animal: the record can only begin after it arose and end before it died out, so either end may reach further. Shares are expected occurrences: a fossil dated to a span is counted partly in each period it straddles. More on what this infers.
