The one of the largest land predators to have ever lived, the mighty Tyrannosaurus rex, just crowned a new king. On March 21st, a team of University of Alberta scientists described the oldest and largest T. rex ever found. Scotty’s unearthed fossils reveals a fairly complete set of bones including a hips, limbs, and a complete skull, but for a complete, set paleontologists still had to use what they knew about T. rex anatomy to fill in the blanks.
Sexually reproducing animals have their sex determined through many mechanisms. Sex in reptiles such as alligators is determined by egg temperature during incubation. Some species, like the clownfish, can be hermaphroditic, shifting from one gender to another depending on the environmental READ MORE
Most fish farming in the ocean uses net cages that float because it is easier to feed and remove fish at the surface and because some fish species require access to air. However, the surface of the ocean experiences a READ MORE
What makes a person choose a certain kind of fish when shopping at the grocery store? A group of German researchers surveyed shoppers to better understand their buying decisions. This makes it easier for aquaculture farmers to be profitable and consumers to be satisfied.
Measuring heart rate continuously can show how long it truly takes for fish to recover from stressful events.
There may be concerns with genetically modified organisms (GMO), but the effectiveness of gene editing in developing more productive plants and animals for the agriculture industry can not be argued. With the rise of cheap and simple gene editing technologies, READ MORE
In 1870, parts of a fossilized bird were found in Kansas and then described by the American paleontologist Othniel Marsh. This new bird, dubbed Ichthyornis dispar, was one of the first fossil birds found in North America, and there was READ MORE
Modern bears, while typically thought of as carnivores, actually have a wide variety of dietary preferences. Some eat only meat while others are omnivores, meaning that they eat both meat and vegetation. Cave bears (Ursus spelaeus), an extinct bear species READ MORE
Many marine organisms have a planktonic form. This means that they drift in the ocean for part of their life until they can find something suitable to attach to and grow. A common example of an animal like this would READ MORE
Be grateful you didn’t live at the same time as a T-rex, because it’s superior biting strength could really mess you up. Scientists at Oklahoma State and Florida State collaborate to understand why that is.
