Australocerambyx chilensis Peña, 1971

Description (Google translation): The tunnels examined inside the fossil wood are readily distinguishable. Their shape is circular, varying in diameter from 2.5 to 4 mm. In sample No. 1 (Fig. 1A), the tunnel has a diameter of 2.5 mm and is partially filled with an opaline-looking agatized substance. Gallery B is vertical to A and cuts the trunk horizontally, horizontally, to the axis of the tree. This gallery is completely covered by this substance, as can be seen in Fig. 2B, and has a diameter of 3.8 mm. In C (Fig. 1), there is another gallery of the same diameter as B, all of which appear to belong to larvae of different ages.

In sample No. 2 (Figs. 4 and 5), the evidence is somewhat irregular, and the gallery can be seen lined with the same agatized substance. The walls are covered with very small crystals. Its diameter is 4 mm. Figure 4 shows the gallery intact, and Figure 5 shows it broken at one end to show its shape.
In sample No. 3, there are four pieces of evidence, two of which are 4 mm in diameter, perpendicular to the tree axis, and two in the opposite direction and of the same diameter, without being covered with an opaline substance.
In sample No. 6, there is another piece of evidence, a perforation that runs perpendicular to the tree axis, also 4 mm in diameter.
There are other samples with similar pieces of evidence that were not numbered.
