Eozygodon

Eozygodon is an extinct genus of proboscidean in the family Mammutidae. It is a monotypic genus that contains the single species E. morotoensis, named in 1983. It is known from the Early Miocene of Africa and well as possibly the Middle Miocene of China. It is considered a primitive member of the family, retaining a long lower jaw (longirostrine) with lower tusks. The upper tusks are small, and are only slightly divergent from each other. The skull of the young adult AM 02 from Auchas, Namibia, was around the size of that of a 10 year old American mastodon, around 60 centimetres (2.0 ft) in maximum length. Some authors suggest that Eozygodon could be less closely related to other members of Mammutidae than other mammutids are to Elephantida, making Mammutidae as typically defined paraphyletic.

Time the record covers

At most 4.4 million years on record.

The one occurrence read is dated to somewhere between 15.98 Mya and 11.63 Mya, which is a dating window rather than a span.

1 occurrence of Eozygodon 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.
