mob model error

so this is the error i keep getting. i cant even delete the mob model because it keeps coming back (dont know from)...

public class Modelram<T extends> extends EntityModel<> {
    // This layer location should be baked with EntityRendererProvider.Context in
    // the entity renderer and passed into this model's constructor
    public static final ModelLayerLocation LAYER_LOCATION = new ModelLayerLocation(new ResourceLocation("fantasia_ii_", "modelram"),
            "main");
    public final ModelPart body;
    public final ModelPart head;
    public final ModelPart leg0;
    public final ModelPart leg1;
    public final ModelPart leg2;
    public final ModelPart leg3;
    public Modelram(ModelPart root) {
        this.body = root.getChild("body");
        this.head = root.getChild("head");
        this.leg0 = root.getChild("leg0");
