Так 150 кг это довольно крупная львица!
А на картинке махайрод подозрительно похож на гомотерия, а борофаг на простого волка.

Находка черепа, кому может принадлежать? SIRENIA SKULL?

A 40 cm long skull found on a Miocene rock... ( Предпологают ,что борофагу?)



In the Miocene, the Lisbon area was completely under ocean's water. It was a warm environment, very similar to what we can find actually in the tropics. The water was filled with life, sharks, crocodiles and turtles, many echinoid and mollusk species, now gone. The Portuguese shore, at the time, was very different from now. The water kept moving back and forward, invading dry land and depositing most of the material that we can find today as fossils. This variation of the sea level, caused temporary lagoons and swamps, giving birth to a series of different environments. Today, the scene is very different. The shore line is well defined, and rocky Miocene cliffs alternate with sandy beaches. This specimen was found in August 1997, at about 13:00, on a burning hot summer day. During a fossil research, near sea water, I've stumbled over a curious fossil, which seemed to be a very symmetric bone. At the time, only about 10 to 15% of the skull could be seen. I figured that it would be big enough to keep me working the rest of the day under a merciless sun. A few hours later, the specimen was out of the rock.

Looking a bit closer to this specimen, I believe that it belongs to a carnivorous species. The lower jaw is missing and the rock where it was found shows no traces of it. Soon, during preparation procedures, the eight teeth appeared and confirmed this theory. A few specialists saw the specimen but they didn't got to any conclusive answer. Some suggested that it belonged to a Borophaginae member, probably equivalent to an Epicyon. But all these are terrestrial predators and this fossil was found in a marine environment. What could have happened? Maybe this beast was old or ill and died near sea shore. The teeth show some marks of erosion at the tips, just like what happens with old animals. Maybe it was taken by a flood and ended in the ocean. It could have been attacked by a crocodile or a shark, while swimming. These theories may explain the fact that this terrestrial animal ended up between marine fossils. The skull also shows some polishment, caused probably by sea erosion before fossilization. This can also explain, by the other hand, the nicks seen on the teeth tips.

At this time it still has no positive ID. Preparation continues and more features are still appearing. Below you can find some links to the specimen photos and to some examples that I've found and gather some of the main characteristics of this find.

Может и эпициону, но обратите внимание на размер 40см?

Я так понимаю эпицион весил где-то 130-150 кг, учитывая такой длинный череп и массивность. Выходит он был высотой с крупного дога и весом как суперразжиревший английский мастиф, но при этом в нормальной кондиции, как любой дикий зверь. Просто страшная собака была.
Перечислите какие тогда крупные хищники водились?

Эпицион жил примерно 10 млн. лет назад, если я не ошибась

По-моему где-то 1 миллион лет назад. Высота в холке эпициона около 90 см.

Есть ещё вопросы.
1.Когда и где жил борофаг?(Вроде бы в Северной Америке, а когда.(После борофага, но когда именно?)).
2.Высота борофага в холке?(80 см?)
3.Какой вид борофага самый крупный?
4.Какая высота в холке у ужасного волка?

Наверное второй лучше, да?

Первый слишком похож на люпуса.

Я думаю дирус вообще не был похож на люпуса.

А по черепу что, можно определить точный облик животного? Форму башки да. Длину и цвет шерсти нет.

"что у дируса были тонкие ножки. Для падальщика это во-первых не характерно"
У энтелодонтов тоже были тонкие ножки.
