I painted an Eocetus schweinfurthi the other day. It's odd that there weren't any proper life reconstructions of it made so far. A lot of Eocetus material got lost during WW2 but we know what it is related to and we even have a skull.
The mating period of European hares starts end of January, beginning of February and ends end of July, beginning of August. The height of the breeding season, is known as "March madness", when the normally nocturnal bucks are forced to be active in the daytime. The boxing usually occurs when a male is being too persistent with a female, chasing her across fields in an attempt to mate.
Right at the beginning of the hare breeding season, in January, is also the best time to see the constellation Lepus.
A modern sand tiger shark (Carcharias taurus) and its 5 m long relative Carcharias cuspidatus from the Oligocene. The size is known from a partial skeleton that was found near Rauenberg in Baden-Württemberg.
At the Scheuerberg of Eberbach in the Odenwald a roughly 250 million years old footprint with a length of 28 cm was found, that may have belonged to an erythrosuchid.
