Thylacosmilus

thylacosmilus

In Depth        With its oversized front teeth Thylacosmilus appears to be very similar to sabre toothed cats like Smilodon.‭ ‬The key difference between these two types of animal is that the sabre toothed cats were placental mammals,‭ ‬which means that young developed while connected to a placenta via an umbilical cord while remaining inside the … Read more

In Depth        Agilodocodon is a genus of small mammaliforme that lived in what is now China during the Mid Jurassic.‭ ‬Agilodocodon is thought to have been an arboreal animal,‭ ‬and as such spent most of its life living in the tree canopy.‭ ‬Here Agilodocodon is thought to have fed mostly upon tree sap,‭ ‬safe and … Read more

Beiyanerpeton

In Depth        Beiyanerpeton was a small salamander-like amphibian that lived in China during the Jurassic.‭ ‬As such it is expected to have been like a modern day salamander in terms of ecological niche,‭ ‬though of course with the addition of possibly being occasional prey to small carnivorous dinosaurs.

Beishanlong

In Depth        The remains of‭ ‬Beishanlong are quite incomplete,‭ ‬but they do tell us that this was an ornithomimosaur and a particularly large one at that.‭ ‬The team of palaeontologists that described the first specimens came up with an estimated length of up to eight meters long,‭ ‬but further study yielded the discovery that the … Read more

In Depth        With three pairs of short blunt horns on top its skull and two tusks that pointed down from the upper jaw,‭ ‬Eobasileus looked remarkably‭ ‬similar to its close relative Uintatherium‭ (‬which is why unsurprisingly it is a member of the Uintatheriidae‭)‬.‭ ‬With an upper size comparable to that of a large black rhinoceros‭ … Read more

Tonganosaurus

In Depth        Tonganosaurus is a genus of sauropod dinosaur that lived in China during the early Jurassic.‭ ‬Tonganosaurus is seen as being similar to Omeisaurus,‭ ‬and both are classified as mamenchisaurid sauropod dinosaurs‭ (‬similar to Mamenchisaurus‭)‬.
