"Lotheridium (meaning "small beast of Luoyang") is an extinct genus of deltatheroidan mammal" I would briefly define what deltatheroidan is in parentheses. Ex for "Pteranodon" I would say ""Pteranodon" is an extinct genus of pterosaurian (a group of flying archosaurs) reptile"

"it has been flattened during fossilization and its roof is therefore crushed." Improve flow, like: it was flattened and had its skull roof crushed during fossilization

"Like in its closest living relatives, the marsupials, the deciduous third premolar is replaced by a permanent one as the animal matures, but the other premolars are retained permanently with no replacement." too specific to include in prose

DISCOVERY AND NAMING

Include something about the age of the Qiupa Fm. and the holotype itself.

any info on who collected it? What expedition? etc.

Description paper doesn't mention any of that. I have found other papers mentioning expeditions to the site in the 2000s that yielded many fossils including mammals but can't find anything more specific or whether Lotheridium was among these.

Description

Give a body measurement if possible*How big is "Deltatheroides"?

No postcranial remains of any member in the order are known to my knowledge so any full body measurement would be quite speculative (not that I can find one anyways so it would be OR). Deltatheroides seems to only be known from jaw fragments so there doesn't seem to be a published estimate of its skull length either, just measurements of those fragments.

" This bone has a large opening called the infraorbital foramen, in front of which the maxilla depresses inward. This depression may have been an attachment point for facial muscles" combine

Classification

"Lotheridium belongs to an extinct order of mammals known as the Deltatheroida, and specifically is a member of the family Deltatheridiidae. " simplify, something like "Lotheridium belongs to the family Deltatheridiidae with in an extinct order of mammals known as the Deltatheroida"

Paleobio & Paleoenviro

"Deltatheroidans such as Lotheridium are believed to have been carnivorous animals. This is supported by the fact that two of the ridges (namely the postmetacrista and preprotocrista) of their upper molars form a prominent mechanism for shearing flesh, which has also convergently evolved in other carnivorous mammals.[3][9] " which carnivorous mammals? state specific

"A study on jaw shapes to predict the feeding ecology of Mesozoic mammals also found that a close relative of Lotheridium known as Deltatheridium would have been a carnivore.[10]" Deltatheridium has already been mentioned as a relative and mentioned in the article
