en.wikipedia.org/wiki/2020_in_mammal_paleontology#Carnivorans Description of the tarsal bones of the bear dogs from the Paleogene of Europe, and a study on the evolution of posture and locomotion of European bear dogs, is published by Fournier et al. (2020). New specimen of Agnotherium antiquum, providing new information on the anatomy of this species, is described from the Miocene locality of Eppelsheim (Germany) by Morlo et al. (2020), who interpret this species as a powerful, strictly carnivorous ambush hunter. A metacarpal bone of a short-faced bear is described from Daisy Cave (San Miguel Island, California Channel Islands) by Mychajliw et al. (2020), who attempt to the determine the most likely explanation of the occurrence of this specimen on San Miguel Island. A study on anatomical specializations in cave bears for longer hibernation periods, and on their impact on feeding biomechanics in cave bears, is published by Pérez-Ramos et al. (2020). A study on the diet of cave bears from cave sites in Romania, as indicated by nitrogen isotope values of individual amino acids from fossil collagen, is published by Naito et al. (2020). A study on the relationship between the shape of tooth crown surfaces and feeding behaviour in living bears, evaluating its implications for the knowledge of likely diet and possible extinction causes of cave bears, is published by Pérez-Ramos et al. (2020).

We need to find more. There are more invertebrates than vertebrates on this planet.

A good possibility for ancient bear discoveries.

If another ancient bear is discovered, that means some of my fictional stories might have to be modified once again.

If another ancient bear is discovered, that means some of my fictional stories might have to be modified once again. Back some years ago, wild animal face-off forums were active and numerous. Probably the most popular one was AVA "Animal vs Animal", not to be confused with a less popular "Animals vs Animals". One thing nearly all had in common; it was either tiger-fan dominated or lion-fan dominated. But, what I have to say, has nothing to do with either. During those years, there were two big bear discoveries. First, the big news about Ursus maritimus tyrannus. The giant sea bear or giant polar bear. This was huge! In the beginning, this giant bear was said to be bigger than Arctodus simus, averaging 2,400 pounds. As time progressed, the bear shrank by several hundred pounds and became more than likely a brown bear. Next, Arctotherium angustidens - the South American giant short-faced bear. Here again, he started out much bigger than we view him today; by about a ton. So now, I am wondering what new discoveries might be dug up.

Massive fossil find in California includes mastodon, petrified forest bigthink.com/the-past/california-fossil-find/#Echobox=1663071712 It soon became clear that Francek had come across one of the most important fossil sites ever discovered in California. A wide variety of fossilized remains have been found in the watershed. There are the ancestors of elephants: mastodons and four-tusked gomphotheres. (The last mastodon fossils discovered in California were found in 1947 during construction of a pipeline in Contra Costa County.) Researchers have also unearthed camel fossils (!) and a massive 400-pound salmon with spiked teeth. Add to the list tapirs, horses, tortoises, and even rhinoceroses. No other site comparable in diversity has ever been found in the Golden State. Shapiro describes the story the fossils tell: “I can look out and picture a movie reel of the lands changing. Through the trees, I see one group of elephants peek out as another walks by, and then great horses come in.” *Note: Could you imagine a grizzly finding a 400-pound salmon
