Features of an animal's skull such as dentition and eye position provide clues about what it eats and where it sits in the food chain. It is also possible to refer to morphological features when discussing animal behaviour, habitat and adaptation. Comparing animal skulls can be a great way to introduce and illustrate a wide range of topics in biology, and we are pleased to introduce three new Comparative Collections from Bone Clones Inc.
What's for dinner? Meat? Insects? Plants? All of the above?
This set consists of four skull casts that exhibit key and distinctive features of their dietary groups:
The diversity in the Canidae family is a great area to begin the discussion of evolution and natural selection. Skull features can be compared and contrasted to demonstrate inheritance, modification and variation of traits.
Features such as overall size, skull shape, tooth size, size of cheek bones and size of sagittal crest help to distinguish canids from one another. Additionally, each skull can be compared to their prospective habitats, bringing into focus discussions of animal adaptation, animal behaviour, ecological and environmental concepts.
This set comprises skull casts of a fox, coyote, wolf and domestic dog.
Predator or prey? Can you tell by looking at an animal which it is?
As well as the overall size of a skull, the dentition (form and number of teeth) and the orientation and position of the eyes contribute a lot of information about whether the animal was predatory or preyed upon.
This set consists of skull casts of a jack-rabbit, a bobcat and a coyote. Perhaps this rhyme can be helpful:
Eyes to the side means likes to hide
Eyes to the front means likes to hunt
