LARGE FOSSIL ANIMAL OF MAESTRICHT.
The large animal, whose fossil remains are found in the quarries of Maestricht, has been deservedly a frequent object of admiration; and the beautiful appearance which its remains possess, in consequence of their excellent state of preservation, in a matrix which admits of their fair display, has occasioned every specimen of this fossil to be highly valued. The lower jaw of this animal, and some other specimens, which were presented by Dr. Peter Camper to the Royal Society, and which are now in the British museum, are among the most splendid and interesting fossils in existence. In 1770, the workmen having discovered part of an enormous head of an animal imbedded in the solid stone, in one of the subterraneous passages of the mountain, gave information to M. Hoffman, who, with the most zealous assiduity, labored until he had disengaged this astonishing fossil from its matrix. But when this was done, the fruits of his labors were wrested from him by an ecclesiastic, who claimed it as being proprietor of the land over the spot on which it was found. Hoffman defended his right in a court of justice; but through the influence employed against him, he was doomed not only to the loss of this inestimable fossil, but to the payment of heavy law expenses. But in time, justice, though tardy, at last arrived; the troops of the French republic secured this treasure, which was conveyed to the national museum.
The length of the cervical, dorsal and lumbar vertebrae, appears to have been about nine feet five inches, and that of the vertebræ of the tail about ten foot; adding to which the length of the head, which may be reckoned, considering the loss of the intermaxillary bones, at least at four feet, we may safely conclude the whole length of the skeleton of the animal to have approached very nearly to twenty-four feet. The head is a sixth of the whole length of the animal; a proportion approaching very near to that of the crocodile, but differing much from that of the monitor, the head of which animal forms hardly a twelfth part of the whole length. The tail must have been very strong, and its width, at its extremity, must have rendered it a most powerful oar, and have enabled the animal to have opposed the most agitated waters, as has been well remarked by naturalists who have examined it. From this circumstance, and from the other remains which accompany those of this animal, there can be no doubt of its having been an inhabitant of the ocean. Taking all these circumstances into consideration, M. Cuvier concludes, and certainly on fair, if not indisputable grounds, that this animal must have formed an intermediate genus between those animals of the lizard tribe which have an extensive and forked tongue, which include the monitors and the common lizards, and those which have a short tongue and the palate armed with teeth, which comprise the iguanas, marbres, and anolis. This genus, he thinks, could only have been allied to the crocodile by the general characters of the lizards.
