The whale's remains suggest it's a smaller relative of Basilosaurus cetoides, which lived along Alabama's coast 34-40 million years ago.
The location of the state of Texas. Paleontology in Texas refers to paleontological research occurring within or conducted by people from the U.S. state of Texas. Author Marian Murray has said that "Texas is as big for fossils as it is for everything else." [1] Some of the most important fossil finds in United States history have come from Texas.
The cetaceans (whales, dolphins and porpoises) are descendants of land-living mammals, the even-toed ungulates. The earliest cetaceans were still hoofed mammals. These early cetaceans became gradually better adapted for swimming than for walking on land, finally evolving into fully marine cetaceans.
It exceeded 3 m (9.8 ft) in length, and would have weighed in at around 200 kg (440 lb), much larger than any other known mustelid, living or extinct. [157] [158] [159] There were other giant otters, like Siamogale, at around 50 kg (110 lb) [160] and Megalenhydris, which was larger than a modern-day giant river otter. [161]
[1] [3] [4] [24] It is assumed that the hunting tactics of Livyatan for hunting whales were similar to that of the modern killer whale, pursuing prey to wear it out, and then drowning it. [1] [25] Modern killer whales work in groups to isolate and kill whales, but, given its size, Livyatan may have been able to hunt alone. [26]
