Below is the recreation model of an extinct creature – can you name the fossil it leaves behind?

Did you know what last week’s object of the week was?

Well done if you knew our featured object last week was a Lemming! These small rodents have short tails and long fur to conserve heat in the Tundra regions where they live. They feed mainly on grasses and remain active instead of hibernating through the harsh winters. Despite their small size they have quite an aggressive nature.

Lemmings breed quickly, so their population can rapidly increase to unsustainable levels before plummeting. Lemmings are forced to migrate in large numbers, even if great risk is involved. This has led to them having a rather ill founded reputation.
